Type of credit card being used in this transaction. This property contains the customer's credit card type. This is automatically computed after the Number is set, but it can also be changed manually. A list of valid card types is included below.

Three digit security code on back of card (optional).

This alphanumeric property contains the three digit Visa "Card Verification Value" (CVV), MasterCard "Card Verification Code" (CVC), or four-digit American Express "Card Identification Number" (CID). This value appears as additional characters embossed on the card signature line following the credit card account number on the back of the credit card. This is an optional property which can be used to determine if the customer is actually in possession of the credit card.

Even if the CVVData is incorrect, the transaction may still be authorized. It is up to the merchant to examine the ResponseCVVResult property and decide whether to honor the transaction or not.

Note: When set to a non-empty value, CVVPresence will be automatically set to cvpProvided. If set to empty string (""), CVVPresence will be automatically set to cvpNotProvided.

Indicates the presence of the card verification value.

This property is used to indicate the presence of CVVData.

The component will automatically set this value to cvpProvided when a CVVData value is specified. You can explicitly specify the CVVPresence indicator by setting this property.

Available values are:

• cvpNotProvided (0)
• cvpProvided (1)
• cvpIllegible (2)
• cvpNotOnCard (3)

This property contains a 1-character code identifying the source of the customer data. The table below shows all supported values for this property.

Expiration month of the credit card specified in Number.

This property contains the expiration date of the customer's credit card, and must be in the range 1 - 12.

Expiration year of the credit card specified in Number.

This property contains the expiration date of the customer's credit card. This property must be in the range 0 - 99, or 2000 - 2099. Any date before the year 2000 or after 2099 cannot be specified.

Determines whether data set to the Number or MagneticStripe fields is validated.

By default, when the Number or MagneticStripe fields are set, the value will be validated and normalized. For instance, "4444-33332222 1111" will be normalized as "4444333322221111" and MagneticStripe data will be parsed for the track specified by EntryDataSource. However, any other non-numerical data entered will cause an exception to be thrown. It may be useful in some gateways to send other data in the Number or MagneticStripe fields, and this can be accomplished by setting IsEncrypted to true. However, please note that in doing so automatic calculation of the CardType may be affected, and the card number will not be verified.

Track data read off of the card's magnetic stripe.

If EntryDataSource is not one of the manually entered enumerations, then this property must be set with the track1 or track2 data from the magnetic stripe on the back of the customer's credit card. This includes everything after but not including the start sentinel (% or ;) and up to but not including the end sentinel (?) and LRC check character. You may only set this property with track 1 or track 2 data, and may not pass both. Use the EntryDataSource property to indicate which track you are sending.

The following example shows how to set the MagneticStripe and EntryDataSource properties if the data read off the card is "%B4788250000028291^TSYS^05121015432112345678?;4788250000028291=05121015432112345678?"

component.CardMagneticStripe = "B4788250000028291^TSYS^05121015432112345678" component.CardEntryDataSource = edsTrack1 or component.CardMagneticStripe = "4788250000028291=05121015432112345678" component.CardEntryDataSource = edsTrack2

Industry regulations do not allow merchants or processors to store track data in any form of persistent storage. Failure to abide by this regulation can result in significant fines and other penalties.

Customer's credit card number for the transaction.

If you're sending the transaction with MagneticStripe data, this property should be left empty.

Customer's street address. This property is used as part of the Address Verification Service (AVS) and contains the customer's street address as it appears on their monthly statement. Only the street number, street name, and apartment number are required in This property. City, state, and zip code are set in the City, State, and Zip properties.

The length of this property varies by gateway. If the customer's address is very long, it is admissible to include only the street number in This property.

NOTE: For the Moneris gateway, this property should contain only the customer's street number. The street name should be added via the AddSpecialField method. For example:

component.CustomerAddress = "123" component.AddSpecialField("avs_street_name", "Nowhere Ln")

A specific detail on the customer's shipping address (such as building, suite, apartment, floor number etc.).

This property allows you to get or set an XML aggregate built from all of the Customer properties. "EPCustomer" is the root element. The Customer properties make up the tags under the root, but without the beginning "Customer". For instance: <EPCustomer> <Address>123 Nowhere Ln.</Address> <Address2>Apt 3B.</Address2> <City>Beverly Hills</City> ... </EPCustomer>

Customer's city. This property is used as part of the Address Verification Service (AVS) and contains the customer's city as it appears on their monthly statement. Other AVS properties include Address, State, and Zip.

Customer's country. This property contains the country in which the customer is located. Most gateways use a two-letter country code, specified in ISO-3166.

Note: If using this property with the PayFuse gateway, this property should contain the ISO-3166 numeric code instead of the standard two-letter code. For example, the ISO code for the US is "840".

Customer's email address. This optional property contains the customer's email address.

Customer's fax number. This optional property contains the customer's fax number.

Customer's first name. This property contains the customer's first name.

Customer's full name. This property contains the customer's full name as it appears on the credit card or bank account. Many gateways use this property in addition to, or instead of, the FirstName and LastName properties. If a gateway requires a FullName and the property is empty, FullName will be constructed using the contents of FirstName and LastName.

Merchant-generated customer Id. This property contains a merchant-generated customer identification number. This number should be unique for each different customer that places an order with the merchant.

Customer's last name. This property contains the customer's last name as it appears on their credit card.

Customer's phone number. This optional property contains the customer's phone number.

Customer's state. This property is used as part of the Address Verification Service (AVS) and contains the two character postal abbreviation of the customer's state as it appears on their monthly statement. Other AVS properties include Address, City, and Zip.

Customer's zip code (or postal code if outside of the USA). This property is used as part of the Address Verification Service (AVS), and contains the customer's zip code as it appears on their monthly statement. Other AVS properties include Address, City, and State.

Contains an authorization code when a transaction has been approved. This property contains an authorization code when a transaction has been approved. If the Code returned indicates that the transaction is not approved, then the contents of this property should be ignored.

Indicates the status of the last transaction. This property will be True if the last transaction was approved. However, you should not rely solely on the value contained in this property. After every transaction, the Code should be inspected and evaluated according to the specifications of the Gateway in use. A list of response codes for each gateway is listed in the table of contents. However, it is recommended that the developer acquire the current list from the Gateway which is being used.

The amount approved for the transaction, this is the amount actually charged to the credit card.

This property is primarily used when gateways allow partial authorizations and AllowPartialAuths is 'True'. Thus this property is not used by all gateways and should not alone be used to determine if a transaction was successful (such as in the case that this property is not populated).

Contains the Address Verification System result code. This one character property contains the Address Verification Service (AVS) result code. An AVS result code can provide additional information concerning the authentication of a particular transaction for which cardholder address verification was requested. An AVS result code of "0" will be returned in the response message when no address verification has been requested. The value returned should be stored for later retrieval, as it may be required when voiding or refunding a transaction. Valid AVS response codes are listed below, and are identical across all Gateway (note that some gateways do not return an AVS response).

Note: Some gateways use their own response codes instead of those in the above table; those response codes are detailed below for such gateways.

Indicates the status of the authorization request. This property contains the actual response code as returned by the Gateway. Unlike the Approved property, this Code property may provide more details about why a transaction was declined. Therefore, it is recommended that developers check the Code as well as the Approved property. The Point of Sale system should evaluate this response code and NOT the Text to determine nature of a response message. The current (at the time of this release) response codes for the supported Gateways are listed in the table of contents to your left.

Contains the returned CVV2 result code if it was requested. This property contains the host returned CVV2 result code (if CVV data was sent in the request). The following is a list of current result codes:

A gateway may also support custom codes or human-readable response messages in this property. Please consult your gateway documentation to determine if CVV2 codes are supported.

Note: Some gateways use their own response codes instead of those in the above table; those response codes are detailed below for such gateways.

Stripe

For Stripe, the property will contain the following possible values:

Worldpay Online

For Worldpay Online, the property will contain one of the following:

The entire response returned from the gateway processor. This property contains the entire response returned from the gateway processor. You may use this to parse additional information that is not returned in the standard response properties.

Additional error code returned by some gateways. If a gateway returns it, this property will contain an additional code that may explain why the transaction was declined. You may also wish to inspect ErrorText for a human-readable description of this ErrorCode.

Additional error description returned by some gateways. If a gateway returns it, this property will contain a human-readable description of the error which occurred (if any). You may also wish to inspect ErrorCode for an accompanying code which may be parsed and used by your application.

Invoice number submitted in authorization request (if applicable). This property contains the Invoice Number submitted in the original transaction, echoed back by the Gateway host.

Response code from the underlying processor. Often times a Gateway will return a Code that indicates only whether the transaction is approved or declined. Many of these also include a secondary code that provides more details as to why the transaction was declined.

Note, for the PayFlowPro Gateway this property will contain a "1" if the transaction was a duplicate, a "-1" if duplicate checking service is unavailable, and will be blank for a successfully authorized transaction.

Text information that describes each response code. This property contains a response or display text message. This message can be used by the terminal to display the authorization result. The display text must not be used to determine the nature of a response message. A Gateway may translate the response according to the language indicated in the merchant account setup (if applicable).

Contains the Visa Transaction Identifier or MasterCard Reference Number. This property contains a transaction identifier or reference number. The Point of Sale (POS) device should not attempt to interpret the meaning of any data appearing in this property. Data returned in this property (if any) should be recorded and used to submit a modification of this transaction at a later time (such as voiding the transaction or capturing an authorization-only transaction, if applicable).

Customer's shipping street address.

A specific detail on the customer's shipping address (such as building, suite, apartment, floor number etc.).

Customer's shipping city.

Customer's shipping country. This property contains the country in which the customer is located. Most gateways use a two-letter country code, specified in ISO-3166.

Customer's last name.

Customer's phone number.

Customer's shipping state.

Customer's shipping zip code (or postal code if outside of the USA).

Name of special configuration field to submit in this transaction. The Name and Value properties can be used to send special gateway configuration and transaction properties for each transaction. These properties can also be used to extend the functionality of this component by submitting additional information to the gateway.

This property is not applicable for the LinkPoint, FirstData, YourPay, PayFuse, or Orbital gateways.

Value of special configuration field to submit in this transaction. The Name and Value properties can be used to send special gateway configuration and transaction properties for each transaction. These properties can also be used to extend the functionality of this component by submitting additional information to the gateway.

Note: This property is not applicable for the LinkPoint, FirstData, YourPay, PayFuse, or Orbital gateways.

This property is used to tell the component which type of authorization to perform when connecting to the proxy. This is used only when the User and Password properties are set.

AuthScheme should be set to authNone (3) when no authentication is expected.

By default, AuthScheme is authBasic (0), and if the User and Password properties are set, the component will attempt basic authentication.

If AuthScheme is set to authDigest (1), digest authentication will be attempted instead.

If AuthScheme is set to authProprietary (2), then the authorization token will not be generated by the component. Look at the configuration file for the component being used to find more information about manually setting this token.

If AuthScheme is set to authNtlm (4), NTLM authentication will be used.

For security reasons, setting this property will clear the values of User and Password.

This property tells the component whether or not to automatically detect and use proxy system settings, if available. The default value is False.

This property contains a password if authentication is to be used for the proxy.

If AuthScheme is set to Basic Authentication, the User and Password are Base64 encoded and the proxy authentication token will be generated in the form Basic [encoded-user-password].

If AuthScheme is set to Digest Authentication, the User and Password properties are used to respond to the Digest Authentication challenge from the server.

If AuthScheme is set to NTLM Authentication, the User and Password properties are used to authenticate through NTLM negotiation.

This property contains the Transmission Control Protocol (TCP) port for the proxy Server (default 80). See the description of the Server property for details.

If a proxy Server is given, then the HTTP request is sent to the proxy instead of the server otherwise specified.

If the Server property is set to a domain name, a DNS request is initiated. Upon successful termination of the request, the Server property is set to the corresponding address. If the search is not successful, an error is returned.

This property determines when to use a Secure Sockets Layer (SSL) for the connection to the proxy. The applicable values are as follows:

This property contains a user name, if authentication is to be used for the proxy.

If AuthScheme is set to Basic Authentication, the User and Password are Base64 encoded and the proxy authentication token will be generated in the form Basic [encoded-user-password].

If AuthScheme is set to Digest Authentication, the User and Password properties are used to respond to the Digest Authentication challenge from the server.

If AuthScheme is set to NTLM Authentication, the User and Password properties are used to authenticate through NTLM negotiation.

Retail Config Settings

This setting is used to pass the 3D Secure authentication status on to the transaction server. This component may be used in conjunction with the ThreeDSecure component or with any other 3D Secure MPI implementation. Other values necessary for passing 3D Secure data include 3DSCAVV, 3DSXID and 3DSECI. This setting is only valid for E-Commerce transactions. Applicable values are:

This setting is used to pass 3D Secure CAVV data on to the transaction server. This field must be formatted as a 28-byte Base-64 encoded value. This component may be used in conjunction with the ThreeDSecure component or with any other 3D Secure MPI implementation. Other values necessary for passing 3D Secure data include 3DSXID and 3DSECI. This setting is only valid for E-Commerce transactions.

This setting is used to pass the directory server transaction Id to the gateway for 3DS 2.0. This component may be used in conjunction with the ThreeDSecure component or with any other 3D Secure MPI implementation. This setting is only valid for E-Commerce transactions. This setting is currently only supported when the Gateway property is set to gwNetbanx.

This contains a 1-character transaction indicator identifying the type of transaction being authorized. Supported values vary between gateways, so please consult gateway documentation for more information. Note: Other values necessary for passing 3D Secure data are 3DSXID and 3DSCAVV. This setting is only valid for E-Commerce transactions.

This setting is used to pass the cardholder's 3D Secure enrollment status to the gateway for 3D Secure 1.0.2. This component may be used in conjunction with the ThreeDSecure component or with any other 3D Secure MPI implementation. This setting is only valid for E-Commerce transactions. This setting is currently only supported when the Gateway property is set to gwNetbanx.

This setting is used to pass the 3D Secure TransactionId (XID) data on to the gateway. This setting must be formatted as a 20-byte plaintext value, or a 28-byte Base-64 encoded value. This component may be used in conjunction with the ThreeDSecure component or with any other 3D Secure MPI implementation. For example: Other settings necessary for passing 3D Secure data are 3DSCAVV and 3DSECI. This setting is only valid for E-Commerce transactions.

When set to 'True', partial authorizations will be allowed and must be handled accordingly. A partial authorization occurs when a customer's available funds for a specific card can only meet a portion of the total TransactionAmount. Therefore a second means of payment must be used to pay for the remaining amount. When such a case occurs, the partially approved amount will be made available via ApprovedAmount. When set to 'False', if a customer's card does not have funds the available to account for the entire TransactionAmount the transaction will be declined. The default value is 'True'.

This configuration setting can be used to specify a single input format for the TransactionAmount property. When set to a value other than 0, the component will automatically convert the amount from the specified format to the format expected by the gateway. Valid values are:

Note that this setting is only designed for use with currencies that have two digits after the decimal point, like US dollars.

This setting specifies the Base-64 encoded data containing the encrypted payment data received from Apple. The encrypted payment data must be retrieved in a separate process by communicating with the Apple Passbook app. Once the encrypted payment data is received from Apple set this configuration setting, which takes the place of Card, and perform either an AuthOnly or Sale transaction to process the payment.

This setting is applicable to the following gateways:

• Authorize.NET (gwAuthorizeNet)
• BlueSnap (gwBlueSnap)

This configuration setting can be used to set the company associated with the shipping address of the customer.

When AllowPartialAuths configuration setting is set to true and there are not enough funds to cover the full transaction amount set using the TransactionAmount property, Authorize.NET will return a Split Tender Id that can be later used, to link to the original partially authorized transaction, to charge the full amount, void, or capture.

This config is used to specify the Key Serial Number (KSN) value after encrypting card magnetic stripe (track) data and is returned using BluePay's encryption tools. Prior to specifying encrypted card data, CardEncrypted should be set to "True".

This setting takes a previous transaction's TransactionId. For any parameters that are not set, BluePay will use values from the referenced transaction.

This config is used to specify the length of the magnetic stripe (track) data prior to it being encrypted using BluePay's encryption tools. Prior to specifying encrypted card data, CardEncrypted should be set to "True".

When set to true, the component will update a prevous transaction when the Sale method is called. BluePayMasterId must be set to the TransactionId of the previous request, and the transaction can only be updated before it has been settled by BluePay.

Set this config to "True" to allow encrypted card track data to be specified and sent in the request. Note that this config must be set to "True" prior to setting MagneticStripe to the encrypted magnetic stripe data, otherwise an exception may be thrown when the component attempts to verify the magnetic stripe data format. The default value is "False".

Note: When using the BASYS, PhoeniXGate, or Repay Gateways, set this configuration setting to True so both Track1 and Track2 Data are sent in the request.

This config allows you to specify the way in which the transaction took place. This config is applicable to the Barclay, HSBC, and PayFuse gateways.

Applicable values are:

This field is used for the gateways the support International card types. Supported gateways include: Adyen, Barclay, CyberSource, FastTransact, HSBC, NetBanx, NetBilling, Orbital, PayFuse, PaymentExpress, PayPoint, PlugNPay, SagePay, SECPay, and WorldPayXML. Switch, Solo, and some Maestro cards have a 1 or 2 digit Issue number printed on the front of the card, directly following the card number. If that issue number is present, it should be set with this config setting.

When set to "True" (default value), in the case of a manually entered card, the transaction will be processed with the card being identified as present. When set to "False", the transaction will be processed as a 'Card Not Present' transaction.

This config is currently applicable to the Heartland gateway.

If there is a Start Date present on the card, set the month here and the year in CardStartYear.

If there is a Start Date on present on the card, set the year here and the month in CardStartMonth.

This config is used to specify the type of credit card being used in a retail transaction. The type will be computed by the component based on the Card data but this value can be specified to override any computed values.

The available card types are:

This property will contain the CAVV response value to the authorization and will be populated along with Response. Values vary between gateways, so please consult gateway documentation for more information.

When true, this setting indicates that the customer gave the merchant permission to perform a Card On File (COF) transaction. Currently only used by CardPointe (gwCardPointe).

This field is used to specify the total convenience fee charged for the transaction. This field is applicable to the FirstDataPayPoint and Litle / Vantiv gateway.

This config is used to specify the currency code to be used in the transaction. Default values and codes vary based on the gateway. This config will be populated with the default value for the gateway when Gateway is set.

For more information on these currency code values, please refer to the ISO 4217 standard as well as the gateway specification.

If not set, "2" is sent by default. Currently only supported in the Orbital and WorldPayXML gateways.

This config is used to specify a request token for authorization update transactions (such as captures, credits, voids, and reversals). This is only applicable when using the Atos interface.

This config allows you to specify a customer Profile Id to process a transaction using the customer's information stored within CyberSource's systems (this is known as Payment Tokenization). When specified, the ProfileId will be sent instead of the card data (when performing an AuthOnly or Sale) and thus the stored card in the customer's profile will be charged. Additionally you can Credit a card on a customer's profile by specifying a Profile Id and a TransactionId of "" (empty string). Please note that the component does NOT support creating, modifying, or deleting customer profiles. These will need to be created using the RecurringBilling component or by other means such as within CyberSource's Business Center.

If CyberSourceVoidMode is set to "Void" (default), VoidTransaction sends a void transaction to cancel a Capture or Credit request. Note a transaction can only be voided if CyberSource has not already submitted the capture or credit request to the processor (this is usually done once a day). If CyberSourceVoidMode is set to "Reverse", a full authorization reversal transaction is sent to reverse a previous authorization (i.e. after performing an AuthOnly transaction). Note in a reversal, it is required that TransactionAmount be set to the full amount authorized (as you cannot partially reverse an authorization).

If this setting is set to "True", the request field values will be XML escaped prior to being sent to the CyberSource gateway. If this setting is set to "False" (default), the component does not perform any XML escaping and the values are sent exactly as specified. The default value is "False".

This field is used to set a 19 or 20-byte Key Sequence Number (KSN). This field is associated with DebitPIN and both are required for Debit Sale transactions.

The following gateways support Debit card transactions:

• gwEprocessing(2)
• gwMerchantPartners(31)
• gwJetPay(65)
• gwBluePay(67)
• gwWorldPayLink(87)
• gwFirstDataPayPoint(90)
• gwPhoeniXGate(97)
• gwRepay(98)
• gwBASYS(106)

This field is used to set a 16-byte encrypted PIN for a Debit card. This field is associated with DebitKSN and both are required for Debit Sale transactions.

The following gateways support Debit card transactions:

• gwEprocessing(2)
• gwMerchantPartners(31)
• gwJetPay(65)
• gwBluePay(67)
• gwWorldPayLink(87)
• gwFirstDataPayPoint(90)
• gwPhoeniXGate(97)
• gwRepay(98)
• gwBASYS(106)

This field is used to specify a dynamic descriptor (sometimes called a soft descriptor) for the transaction. Typically this value is used to specify transaction specific details which will be displayed on the customer's credit card statement.

The following gateways currently support this functionality: Heartland.

When set to true, this config will cause the component to automatically escape the XML data in the request. The default value is false. This is currently only supported in the Authorize.Net XML gateway.

When returned in the response, this field will be populated with the current balance on the card used to process the transaction.

This field is used to specify the gift card transaction type you wish to perform. All gift card transactions are performed by setting the type via this config and calling the Sale method. When the transaction type is set to '0', the Sale, VoidTransaction and Refund methods can be called to perform their respective transactions. Note to process a gift card transaction, FDMSProcessGiftCard must be set to 'True'.

Applicable values are:

This config is used to specify the Key Id, obtained from FDMS, that corresponds to the HMAC Key (specified via HashSecret) and is sent within the Authorization header of the request.

When set to 'True', the current transaction will be run as a gift card transaction. The default value 'False', will perform a regular credit card transaction.

This config is used to both retrieve and specify a Transarmor Token for the First Data E4, Payeezy, and Bank Of America gateways. If your account is configured for Transarmor tokens, a token will be created by the server and returned via this config when performing a transaction using a Card data. Additionally, you can set this config to a previously retrieved token value and the token will be sent in the request rather than the Card data. This increases security as raw card data is no longer needed. Note when sending an FDMSTransArmorToken value, the CardType, ExpMonth, and ExpYear are required.

This field is used to specify a wallet provider when using a digital wallet like Apple Pay or Android Pay. By default this field is not sent, and no wallet provider is used.

Applicable values are:

This config is used to specify the refund password provided to you by Global Iris. When a refund is performed, the component will use the specified password to generate and send a 'refundhash' in the request. This value is required when performing a Refund transaction.

By default, the Password property is sent as the "password" field in all requests. If the GoEMerchantUseGatewayId configuration setting is set to True, the component will instead treat the password as the "gateway_id" field in all requests.

Certain gateways allow the request to be hashed as an additional authentication mechanism. This configuration setting controls which algorithm is used for hashing. Valid values are:

Some gateways allow for the generation of a hash for added security. The following gateways support this config.

Authorize.Net: The newest version of the protocol includes an optional Hash Secret, which may be used to verify that a server response is actually from an Authorize.Net server. The hash secret is concatenated with the MerchantLogin, TransactionId, and TransactionAmount. This value is then hashed with the MD5 algorithm and compared to the value returned by the server. If they do not match, the component raises an exception. If the AIMHashSecret is left blank, this check will not be performed. The Server's Hash Secret may be set using the Authorize.Net online merchant interface, located at https://secure.authorize.net/.

Bank of America: This value will be the HMAC Key generated for you by the gateway. This value is required and an exception will be thrown if not specified.

BarClay and Ingenico: This value is optional and when specified 'SHASIGN' parameter will be computed and sent.

Bambora/Beanstream: If hash validation is required then set this to your hash key. HashAlgorithm will also need to be set accordingly.

Nuvei: This value is required in all transactions. The value is unique to each terminal and can be set through the online interface at "https://testpayments.nuvei.com/merchant/selfcare/".

USAePay: This value is optional and when a 'Pin' value is specified, the 'UMhash' parameter will be computed and sent.

If HeartlandDeveloperId is set, the HeartlandVersionNumber should also be set. If set, this field must be exactly 6 characters in length.

This is issued by Heartland during registration.

This is issued by a Heartland Payment Systems Administrator during registration.

The Heartland gateway supports reversals of credit card transactions. To perform a reversal, TransactionAmount can be set and the VoidTransaction can be called. When performing a reversal, TransactionAmount must be set to the original authorized amount of the transaction you are performing the reversal on. This field should then be set to the settlement amount of the transaction (or the final authorized amount after the reversal is performed).

If Heartland provides a secret key for use with their API, this property can be used to send it to the gateway. When this key is set, the HeartlandLicenseId, HeartlandSiteId, HeartlandDeviceId, MerchantLogin and MerchantPassword are not required, and will not be sent to the gateway.

The ship day for the Heartland transaction. Valid values are 1 - 31.

The ship month for the Heartland transaction. Valid values are 1 - 12.

This is issued by Heartland during registration.

Heartland supplies an additional way to trace the transaction, beyond the InvoiceNumber and TransactionId.

The field is used to specify the type of token that should be returned when using the Heartland gateway. By setting this field to a value other than 0 (None), a Token will be requested and returned in the response via HeartlandTokenValue (provided one can be generated). Please see the "ICharge Gateway Setup and Required Properties" page for more details about using tokenization, as there are special merchant account configurations required.

The available mapping values are:

This field is used to retrieve a Heartland Token value when using Heartland Tokenization (which is accomplished by setting HeartlandTokenMapping to a value greater than 0). A token replaces the card number in all subsequent transactions thus increasing security. This field can also be used to specify a previously retrieved token value. When set, the specified token value will be sent in the request instead of the card number.

If HeartlandVersionNumber is set, the HeartlandDeveloperId should also be set. If set, this field must be exactly 4 characters in length.

This field is used to specify the Id for the AdvancedFraudChecks element for the Litle gateway. Custom attributes can also be included by using the AddSpecialField method with the name "CustomAttributeX", where X is a number from 1 to 5. For example: icharge.Config("LitleAdvancedFraudChecksId=ASDFG-AXXXXAB999"); icharge.AddSpecialField("CustomAttribute1", "One"); icharge.AddSpecialField("CustomAttribute2", "Two");

This config is used to specify the method used to identify the customer when performing a retail transaction.

The available values are (if not specified, the component will send 'signature' by default):

This field is used to specify an XML aggregate for Custom Billing support within the Litle gateway. When specifying custom billing, you can use either the phone or url child.

Below is a sample XML aggregate for the phone child: <phone>555-555-5555</phone> <descriptor>Billing Descriptor</descriptor>

Below is a sample XML aggregate for the url child: <url>retail.url</url> <descriptor>www.retail.com</descriptor>

The HSBC and PayFuse gateway both allow for a merchant alias to be specified (and in some cases it may be required). This field allows you to specify the alias.

For the CardPointe gateway, this configuration setting is required, and should contain your Merchant Id.

For the Litle gateway, this configuration setting is required, and should contain your Merchant Id.

For the MIT gateway, this configuration setting is required, and should contain your Merchant Number (Contado).

For the Priority Payment Systems gateway, this configuration setting is required, and should contain your Merchant Id.

For the WorldPayXML gateway, this configuration setting is optional; it is only needed if you require that the "merchantCode" sent in the request be different from your MerchantLogin (e.g., when processing AMEX transactions, or when supporting multiple currencies).

The last 4 digits of the card number are required to process transactions using a stored profile Id (via MerchantPartnersProfileId) for the MerchantPartners or WorldPay Link gateways.

This field is used to specify the Profile Id of a stored profile and is used to process a transaction instead of specifying the card data. A profile is created via the RecurringBilling component and the SubscriptionId response field is used to obtain the profile Id to be set in this field. MerchantPartnersLast4Digits is a required field when using a stored profile. Note this config is only applicable to Sale and Credit transactions processed via the MerchantPartners or WorldPay Link gateways.

This setting is used to specify the encrypted reader type used to read and encrypt a swiped card. The specified value is sent in the request and is used by the gateway to decrypt the card data so the transaction can be processed.

This field is used to specify the company reference number for the MIT gateway (Required).

This field is used to specify the country of operation for the MIT gateway (Required).

This field is used to specify the encryption algorithm to use for the MIT gateway. Encryption will only be performed if an encryption key is specified via MITEncryptionKey. Note when perform AES (1) encryption, you must also set MITAESSeedId.

Applicable values are:

This field is used to specify the encryption key for the MIT gateway. When set, the specified key will be used to perform the encryption specified via MITEncryptionAlgorithm.

When making a Merchant Initiated Transaction (MIT), this configuration setting should be set to true to indicate to the payment gateway that the transaction is merchant initiated. Used by the Orbital payment gateway.

When making a Merchant Initiated Transaction (MIT), this configuration setting can be used to specify the transaction Id of a previously successful authorization. Used by the Orbital and CyberSource payment gateways.

When this field is set to 'True', the component will perform a recurring transaction request when Sale is called. The fields required for a Recurring charge transaction are the same as a Sale transaction. The default value is 'False'.

This field is used to specify the operation type for the MIT gateway (Required). This value will be provided to you by MIT.

When making a Merchant Initiated Transaction (MIT), this configuration setting is used to specify the type or reason for the merchant initiated transaction. The possible values and formats for this field vary by gateway, so check the gateway's documentation for the associated values and their meanings.

The field is used to indicate whether to use the NVP API for either the gwMoneris or gwMonerisUSA gateway. When set to true, the NVP API will be used instead of the XML specification. Note that you must set Gateway to either gwMoneris or gwMonerisUSA prior to setting this field. Additionally, if you decide to use the NVP API, this field must be set directly after setting Gateway (as GatewayURL will be updated). Note: The Response Method of the DirectPost configuration must be set to "Displayed as key/value pairs on our server" in the merchant admin console when using the NVP API.

This field is used to override the default transaction type for the MyVirtualMerchant gateway. By default, the component will set the transaction type based on the method called. However this field can be set to override the default value and is particularly useful for creating recurring or installment billing transactions. Below is a list of some of the available transaction types. Note that these additional transaction types require special fields to be added via AddSpecialField. Please consult the Virtual Merchant specifications for details about the required fields.

• CCCOMPLETE
• CCADDINSTALL
• CCADDRECURRING
• CCINSTALLSALE
• CCRECURRINGSALE

This field is used to specify your MyVirtualMerchant user Id which is required (along with MerchantLogin and MerchantPassword) as part of the user authentication.

This field is used to specify an account number for the Netbanx gateway which is used in addition to the MerchantLogin and MerchantPassword properties.

The Version portion of the User-Agent HTTP header is required by NetBilling. The default value is "1".

This config is used to specify whether VoidTransaction should perform an authorization reversal or void transaction. When this config is set to 'True' and VoidTransaction is called, an authorization reversal transaction will be sent to reverse a previously authorized transaction. The default value is 'False' which sends a void transaction.

If OrbitalConnectionPassword is set, the OrbitalConnectionUsername should also be set. This field is case-sensitive.

If OrbitalConnectionUsername is set, the OrbitalConnectionPassword should also be set.

Note: This field is auto-populated to "NO" when OrbitalCustomerProfileFromOrderInd is set.

This field is used when performing a VoidTransaction to identify unique components of transactions adjusted more than one time. The default value ("NULL") should be submitted when voiding a transaction which has not been adjusted more than once or if the un-captured remainder of a split transaction (partial capture) should be voided. To void a specific partial capture, this field should be set to the value returned in the response for the partial capture. Note that this field will also be populated with the TxRefIdx value returned in a response.

This field is used to specify an amount to adjust a previous authorization when performing a VoidTransaction. Thus the specified amount will be voided (assuming that the amount is not greater than the transaction amount remaining) and the total amount minus the adjusted amount will be the new authorized amount. When a value is not specified, the full amount of will be voided.

This field is used to specify the total convenience fee charged for the transaction when using the PayDirect gateway. This field is always required when using the PayDirect gateway. The sum of this field plus PayDirectMerchantAmount must always equal the value in TransactionAmount. If no values are set for either of these two configs, the component will set PayDirectMerchantAmount to the value specified in TransactionAmount and PayDirectConvenienceFee to "0.00".

This field is used to specify the total amount of goods and services for the external client when using the PayDirect gateway. This field is always required when using the PayDirect gateway. The sum of this field plus PayDirectConvenienceFee must always equal the value in TransactionAmount. If no values are set for either of these two configs, the component will set PayDirectMerchantAmount to the value specified in TransactionAmount and PayDirectConvenienceFee to "0.00".

This field is used to set Settle Merchant Code assigned by Link2Gov for the Reconciliation of funds. This field is always required when using the PayDirect gateway.

This config is used to specify the IP address of the payer, which is required by some gateways.

Set this config to the TransactionId from the transaction you wish to retrieve. You may also call PFPInquiry without setting it to anything. In this case the Id property is required, and the PayFlow Pro gateway will return the most recent transaction for the specified Id.

This field is used to specify a token value to perform additional authorizations (via Sale or AuthOnly) and Credits (via Credit) without sending card data again. For the Payflow Pro gateway, token values are the same as the TransactionId value returned from an authorization. Below is a code example of how this config can be used (note the code starts after the initial Sale or AuthOnly transaction has been performed):

ICharge.Config("PayFlowProToken=" + ICharge.Response.TransactionId); ICharge.TransactionId = "2"; ICharge.TransactionAmount = "10.00"; ICharge.Sale();

This is an actionable config which when called will send an upload transaction to the Payflow Pro gateway. An upload transaction is used to store credit card information on the gateway server. Note that billing and shipping information can be saved as well. After a successful upload, TransactionId will contain the token value that corresponds to the credit card data stored. This token value can then be used to process transactions via PayFlowProToken.

This field allows you to specify whether Capture will send an update amount or a capture request. By default, this value is 'False', which sends a capture request to mark an AuthOnly transaction for capture. This particular function does not allow you to alter the amount but instead just marks the authorized amount (from the AuthOnly transaction) for capture. When this field is set to 'True', the Capture method will send an update amount request allowing you to alter the amount that will be captured. This method can be used after AuthOnly and Sale transactions.

This field is used to specify the client code that is assigned by 3DSI. This code uniquely identifies your organization for the purpose of accessing and authenticating to the Payment WorkSuite.

This field is used to specify the location code that uniquely identifies a specific location that is associated with the merchant identified by the specified PaymentWorkSuiteMerchantCode.

This field is used to specify the merchant code that uniquely identifies a specific merchant within the Payment WorkSuite.

The field is used to indicate whether to use the Freedom API for either the gwPayPoint and gwSECPay gateway. When set to true, the Freedom API will be used instead of the XML Hosted specification. Note that you must set Gateway to either gwPayPoint or gwSECPay prior to setting this field. Additionally, if you decide to use the Freedom API, this field must be set directly after setting Gateway (as GatewayURL will be updated).

This config is used to add Purchase Card (Level2 and Level3) Data to an existing sale transaction for the PayTrace gateway. The Level2Aggregate and Level3Aggregate fields can be set to specify the purchase card data you wish to add prior to calling this config. A TransactionId, from the response of the original sale, is required to be specified when calling this config; i.e.: ICharge.Config("PayTraceAddPurchaseCardData=123456789");

This value is assigned by PayTrace and is used for validation and tracking purposes. The default value is: "90000035NSFT".

This field is used to specify card token value that you retrieved from Protect.js (see PayTrace documentation for details). This field must be set prior to performing a transaction using a token value instead of a Card.

Note that this is only valid when calling Sale or AuthOnly methods and the Gateway property is set to gwPayTraceJSON (117)

This field is used to specify the encryption key that you retrieved from Protect.js (see PayTrace documentation for details).

Note that this is only valid when calling Sale or AuthOnly methods and the Gateway property is set to gwPayTraceJSON (117)

This is an Action config. Getting this config will cause the component to obtain a Client Key (PROTECT AUTH TOKEN) from PayTrace. The Client Key will be used to authorize your application to use Protect.js to retrieve Card Token (hpf token) and Encryption Key (enc key). Please see PayTrace documentation for details. This key is valid for 20 minutes. icharge = new Icharge(); icharge.Gateway = IchargeGateways.gwPayTraceJSON; icharge.GatewayURL = "https://api.paytrace.com"; icharge.MerchantLogin = bearerToken; string clientKeyToken = component.Config("PayTraceJSONGetClientKeyToken"); //use this key to obtain "hpf_token" and "enc_key" from Protect.js

This configuration setting is used to send an Apple Pay PKPaymentToken containing a user's credentials to a gateway. The setting should be set to the full JSON contents of the PKPaymentToken, like: icharge.Config("PKPaymentToken={\"version\":\"EC_v1\",\"data\":\"...\",\"signature\":\"...\",\"header\":{\"applicationData\":\"...\",\"transactionId\":\"...\",\"ephemeralPublicKey\":\"...\",\"publicKeyHash\":\"...\"}}"); PKPaymentToken is currently only supported in gwLitle.

When using the QBMS gateway, this setting specified whether a transaction is being sent from a mobile device ("True") or not ("False"). The default value is "False".

When using the QBPayments gateway, this setting specified whether a transaction is being sent from a mobile device ("True") or not ("False"). The default value is "False".

This may be queried after a call to any method that sends data to the gateway. This will return the request data that was sent to the gateway which may be useful for troubleshooting purposes. For instance: component.Sale() MyString = component.Config("RawRequest")

This may be queried after a call to any method that sends data to the gateway. This will return the response that was received to the gateway which may be useful for troubleshooting purposes. For instance: component.Sale() MyString = component.Config("RawResponse")

This configuration setting can be set to indicate that a request is a recurring transaction. For a list of supported values for a gateway, please see the "ICharge Gateway Setup and Required Properties" page. This configuration setting is used by the QBPayments gateway.

This is an action config which when called will send a create token request to the SagePay gateway. A successful response will contain the SagePayToken for the specified Number. Note: when using this config you must set the "VPSProtocol" SpecialFields to "3.00".

This is an action config which when called will send a remove token request to the SagePay gateway. The specified SagePayToken will be removed from the SagePay server. Note: when using this config you must set the "VPSProtocol" SpecialFields to "3.00".

This is an action config which when called will perform a Repeat transaction for the SagePay gateway. The 'TransactionId' from a previous authorization response, that you would like to repeat for the card associated with the transaction, must be specified as a parameter. For example, a Repeat transaction using a TransactionId of 123 would be: ICharge.Config("SagePayRepeat=123").

"RelatedSecurityKey" and "RelatedVendorTXCode" special fields are required for Repeats. These are parsed out of the original authorization response.

This field allows you to specify whether to have SagePay generate a token and send it in the response. When set to 'True', a token will be returned in a Sale or AuthOnly response and can be accessed via SagePayToken. Note: when using this config you must set the "VPSProtocol" SpecialFields to "3.00". The default value is 'False'.

This field allows you to specify whether to store a token and on the SagePay server. This field must be set to 'True' to have the token remain on the server after use. Otherwise, if set to 'False', the Token will be used to perform the requested transaction and then deleted from the server. Note: when using this config you must set the "VPSProtocol" SpecialFields to "3.00". The default value is 'False'.

This field is used to retrieve or specify a token value. This field will be populated after a call to either SagePayCreateToken or SagePayRequestToken is set to 'True' and a Sale or AuthOnly request is performed. This field can be specified prior to calling SagePayRemoveToken or performing a transaction using a token value instead of Card.

The SagePay gateway (formerly Protx) has two different void transaction types. If SagePayUseAbort is set to false (default), void transactions are sent with the VOID transaction type. If true, void transactions are sent with the ABORT transaction type. Aborts are used for voiding auth-only transactions, and voids are used for voiding sale/capture transactions.

The TransactionId from the original request must be passed as the parameter in the VoidTransaction method. In addition, the following Special Fields are required for both Abort and Void transactions:

This configuration setting is used to specify the AuthToken to include when making an Access Token Exchange request to the Shift4 gateway. An access token is required for any other interaction with the gateway.

This configuration setting is used to specify the Client Guid to include when making an Access Token Exchange request to the Shift4 gateway. An access token is required for any other interaction with the gateway.

This is an action config which when called will perform an Access Token Exchange request with the Shift4 gateway. Before calling this config, the MerchantLogin property and the Shift4InterfaceName, Shift4InterfaceVersion, Shift4AuthToken, and Shift4ClientGuid configuration settings should be set. MerchantPassword will be set to the access token if the request is successful. Note that an AuthToken can only be exchanged for an access token once, so be sure to save the result of the request for future use.

Shift4 requires you to identify the interface that you are using to communicate with the API (i.e. your application). This configuration setting is used to specify the name of the interface.

Shift4 requires you to identify the interface that you are using to communicate with the API (i.e. your application). This configuration setting is used to specify the version of the interface.

For the Stored Credentials framework, this configuration setting should be set to true to indicate that the merchant will be storing the customer's card information. Permission should be obtained from the customer prior to storing card data. This configuration setting is used by the CyberSource gateway.

This configuration setting is used when there is an additional fee included in the transaction to specify the amount of that fee. This field is used by the Shift4 gateway.

This config is used to specify the capability of the terminal being used in a retail transaction.

The available values for the CyberSource gateway are (If not specified, the component will set the value to either '2' or '3' based on the specified EntryDataSource.):

The available values for the Litle gateway are (If not specified, the component will set the value to 'magstripe'.):

For Shift4 this field is more complicated, and should be set to a JSON object matching the value of the device.capability field from the Shift4 documentation.

Many gateways allow/require an Id (terminal, developer, client, user, etc) sent in addition to the MerchantLogin and MerchantPassword. This config is supported for the following gateways: Adyen (required), BarClay (required), BluePay, Nuvei (required), Heartland, HSBC (required), Orbital, PayFuse (required), PaymentWorksuite, Planet Payment (required), SkipJack, and WorldPayXML (required). For Orbital, this config is optional but if not specified a value of '001' will be sent. For Heartland, this config is used for MasterCard's Card Accepter Terminal Id requirement.

This config is used to specify the manufacturer of the terminal (device) being used in a retail transaction. This config is used with the Shift4 gateway.

This config is used to specify the model of the terminal (device) being used in a retail transaction. This config is used with the Shift4 gateway.

The available values for Chase, First Data, LinkPoint, and YourPay are (required):

This configuration setting is used when there is a tip included in the transaction to specify the amount of the tip. This field is used by the Shift4 gateway.

This field is used to specify whether you wish to perform a void or void:release transaction when VoidTransaction is called. When set to "True", the void:release transaction will be sent. The void:release transaction is the same as a void with the exception that the cardholders bank is notified immediately that they can release the funds. The regular void transaction, on the other hand, does not notify the cardholder bank until the batch closes. The default value is "False" (so a regular void transaction is sent).

For the Stored Credentials framework, this configuration setting should be set to true to indicate that the merchant is using stored card information. This configuration setting is used by the CyberSource gateway.

This configuration setting is used to specify an Id for the user, if one is required. Used by the Barclay, Ingenico, Metrobank, and Shift4 gateways. For the Barclay and Ingenico gateways, this configuration setting should contain the name of your application (API) user. For Shift4 or Metrobank, this is the clerk or terminal operator.

The number of child attributes of the current element. The XChildren configuration options will be indexed from 0 to XChildrenCount-1.

The current element is specified via the XPath configuration option.

This configuration option is read-only.

Provides the name of the x'th child element of the current element.

The current element is specified via the XPath configuration option.

This configuration option is read-only.

Provides the inner text of the x'th child element of the current element.

The current element is specified via the XPath configuration option.

The current element is specified via the XPath configuration option.

This configuration option is read-only.

XPath implements a subset of the XML and JSON XPath specification, allowing you to point to specific elements in the XML or JSON documents. The path is a series of one or more element accessors separated by '/'. The path can be absolute (starting with '/') or relative to the current XPath location. The following are possible values for an element accessor:

When XPath is set to a valid path, XElement points to the name of the element, with XChildren and XText providing other properties of the element.

Example (Setting XPath for XML)

Example (Setting XPath for JSON)

The current element is specified in the XPath configuration option.

This configuration option is read-only.

HTTP Config Settings

When AllowHTTPCompression is True, the component adds an Accept-Encoding header to the request being sent to the server. By default, this header's value is "gzip, deflate". This configuration setting allows you to change the value of the Accept-Encoding header. Note: The component only supports gzip and deflate decompression algorithms.

This configuration setting enables HTTP compression for receiving data. When set to True (default), the component will accept compressed data. It then will uncompress the data it has received. The component will handle data compressed by both gzip and deflate compression algorithms.

When True, the component adds an Accept-Encoding header to the outgoing request. The value for this header can be controlled by the AcceptEncoding configuration setting. The default value for this header is "gzip, deflate".

The default value is True.

This configuration setting controls whether HTTP/2 connections are permitted to fall back to HTTP/1.1 when the server does not support HTTP/2. This setting is applicable only when HTTPVersion is set to "2.0".

If set to True (default), the component will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the component raises an exception if the server does not support HTTP/2.

The default value is True.

This configuration setting determines whether data will be appended when writing to LocalFile. When set to True, downloaded data will be appended to LocalFile. This may be used in conjunction with Range to resume a failed download. This is applicable only when LocalFile is set. The default value is False.

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

This property is provided so that the HTTP component can be extended with other security schemes in addition to the authorization schemes already implemented by the component.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form 'Basic [encoded-user-password]'.

This configuration setting returns the raw number of bytes from the HTTP response data, before the component processes the data, whether it is chunked or compressed. This returns the same value as the Transfer event, by BytesTransferred.

This is applicable only when UseChunkedEncoding is True. This setting specifies the chunk size in bytes to be used when posting data. The default value is 16384.

If set to True, the body of a PUT or POST request will be compressed into gzip format before sending the request. The "Content-Encoding" header is also added to the outgoing request.

The default value is False.

If set to True, the URL passed to the component will be URL encoded. The default value is False.

This option determines what happens when the server issues a redirect. Normally, the component returns an error if the server responds with an "Object Moved" message. If this property is set to 1 (always), the new URL for the object is retrieved automatically every time.

If this property is set to 2 (Same Scheme), the new URL is retrieved automatically only if the URL Scheme is the same; otherwise, the component raises an exception.

Note: Following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is 0 (Never). In this case, redirects are never followed, and the component raises an exception instead.

Following are the valid options:

• 0 - Never
• 1 - Always
• 2 - Same Scheme

The default value is False. If set to True, the component will perform a GET on the new location. Otherwise, it will use the same HTTP method again.

HTTP/2 servers maintain a dynamic table of headers and values seen over the course of a connection. Typically, these headers are inserted into the table through incremental indexing (also known as HPACK, defined in RFC 7541). To tell the component not to use incremental indexing for certain headers, and thus not update the dynamic table, set this configuration option to a comma-delimited list of the header names.

This property specifies the HTTP version used by the component. Possible values are as follows:

• "1.0"
• "1.1" (default)
• "2.0"
• "3.0"

When using HTTP/2 ("2.0"), additional restrictions apply. Please see the following notes for details.

HTTP/2 Notes

When using HTTP/2, a secure Secure Sockets Layer/Transport Layer Security (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/2 will result in an error.

If the server does not support HTTP/2, the component will automatically use HTTP/1.1 instead. This is done to provide compatibility without the need for any additional settings. To see which version was used, check NegotiatedHTTPVersion after calling a method. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.

HTTP/3 Notes

HTTP/3 is supported only in .NET and Java.

When using HTTP/3, a secure (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/3 will result in an error.

If this setting contains a nonempty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the component throws an exception

The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example: Sat, 29 Oct 2017 19:43:31 GMT.

If True, the component will not send the Connection: Close header. The absence of the Connection header indicates to the server that HTTP persistent connections should be used if supported. Note: Not all servers support persistent connections. You also may explicitly add the Keep-Alive header to the request headers by setting OtherHeaders to Connection: Keep-Alive. If False, the connection will be closed immediately after the server response is received.

The default value for KeepAlive is False.

If the Service Principal Name on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, the Service Principal Name should be set here.

This configuration setting controls the level of detail that is logged through the Log event. Possible values are as follows:

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

When FollowRedirects is set to any value other than frNever, the component will follow redirects until this maximum number of redirect attempts are made. The default value is 20.

This configuration setting may be queried after the request is complete to indicate the HTTP version used. When HTTPVersion is set to "2.0" (if the server does not support "2.0"), then the component will fall back to using "1.1" automatically. This setting will indicate which version was used.

This configuration setting can be set to a string of headers to be appended to the HTTP request headers.

The headers must follow the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF ('#13#10') .

Use this configuration setting with caution. If this configuration setting contains invalid headers, HTTP requests may fail.

This configuration setting is useful for extending the functionality of the component beyond what is provided.

This is similar to the Authorization configuration setting, but is used for proxy authorization. If this configuration setting contains a nonempty string, a Proxy-Authorization HTTP request header is added to the request. This header conveys proxy Authorization information to the server. If User and Password are specified, this value is calculated using the algorithm specified by AuthScheme.

This configuration setting is provided for use by components that do not directly expose Proxy properties.

This configuration setting is provided for use by components that do not directly expose Proxy properties.

This configuration setting is provided for use by components that do not directly expose Proxy properties.

This configuration setting is provided for use by components that do not directly expose Proxy properties.

This configuration setting is provided for use by components that do not directly expose Proxy properties.

This configuration setting returns the complete set of raw headers as sent by the client.

This setting contains the first line of the last response from the server. The format of the line will be [HTTP version] [Result Code] [Description].

This configuration setting contains the contents of the last response from the server.

If TransferredDataLimit is set to 0 (default), no limits are imposed. Otherwise, this reflects the maximum number of incoming bytes that can be stored by the component.

This configuration setting returns the complete set of raw headers as received from the server.

This configuration setting returns the full request as sent by the client. For performance reasons, the request is not normally saved. Set this configuration setting to ON before making a request to enable it. Following are examples of this request:

.NET Http http = new Http(); http.Config("TransferredRequest=on"); http.PostData = "body"; http.Post("http://someserver.com"); Console.WriteLine(http.Config("TransferredRequest")); C++ HTTP http; http.Config("TransferredRequest=on"); http.SetPostData("body", 5); http.Post("http://someserver.com"); printf("%s\r\n", http.Config("TransferredRequest"));

If UseChunkedEncoding is set to True, the component will use HTTP-chunked encoding when posting, if possible. HTTP-chunked encoding allows large files to be sent in chunks instead of all at once. If set to False, the component will not use HTTP-chunked encoding. The default value is False.

Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.

This configuration setting specifies whether hostnames containing non-ASCII characters are encoded to internationalized domain names. When set to True, if a hostname contains non-ASCII characters, it is encoded using Punycode to an IDN (internationalized domain name).

The default value is False and the hostname will always be used exactly as specified. Note: The CodePage setting must be set to a value capable of interpreting the specified host name. For instance, to specify UTF-8, set CodePage to 65001.

This configuration specifies whether the component will attempt to use the Proxy auto-config URL when establishing a connection and AutoDetect is set to True.

When True (default), the component will check for the existence of a Proxy auto-config URL, and if found, will determine the appropriate proxy to use.

This is the value supplied in the HTTP User-Agent header. The default setting is "IPWorks HTTP Component - www.nsoftware.com".

Override the default with the name and version of your software.

TCPClient Config Settings

This setting determines whether the input or output stream is closed after the transfer completes. When set to True (default), all streams will be closed after a transfer is completed. In order to keep streams open after the transfer of data, set this to False. the default value is True.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the component will use Timeout for establishing a connection and transmitting/receiving data.

This configuration setting is provided for use by components that do not directly expose Firewall properties.

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

Note: This setting is provided for use by components that do not directly expose Firewall properties.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the component raises an exception.

Note: This setting is provided for use by components that do not directly expose Firewall properties.

The FirewallPort is set automatically when FirewallType is set to a valid value.

Note: This configuration setting is provided for use by components that do not directly expose Firewall properties.

The appropriate values are as follows:

Note: This setting is provided for use by components that do not directly expose Firewall properties.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the component raises an exception.

Note: This setting is provided for use by components that do not directly expose Firewall properties.

When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the component returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.

If the component is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

This must be set before a connection is attempted. It instructs the component to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

When true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this config is set to false.

When set to 0 (default), the component will use IPv4 exclusively. When set to 1, the component will use IPv6 exclusively. To instruct the component to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are:

SSL Config Settings

When SSLProvider is set to Internal, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful for debugging purposes.

When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.

Enabling this setting has no effect if SSLProvider is set to Platform.

This functionality is available only when the provider is OpenSSL.

The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). OpenSSL recommends to use the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

This functionality is available only when the provider is OpenSSL.

The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by

-----BEGIN CERTIFICATE-----

... (CA certificate in base64 encoding) ...

-----END CERTIFICATE-----

sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

This functionality is available only when the provider is OpenSSL.

The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".

This functionality is available only when the provider is OpenSSL.

By default OpenSSL uses the device file "/dev/urandom" to seed the PRNG and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.

If set to true, the component will reuse the context if and only if the following criteria are met:

• The target host name is the same.
• The system cache entry has not expired (default timeout is 10 hours).
• The application process that calls the function is the same.
• The logon session is the same.
• The instance of the component is the same.

This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----
MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp
..

-----END CERTIFICATE-----

This setting specifies whether the component will check the Certificate Revocation List specified by the server certificate. If set to 1 or 2, the component will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The component will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the component raises an exception.

When set to 0 (default) the CRL check will not be performed by the component. When set to 1, it will attempt to perform the CRL check, but will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

This setting specifies whether the component will use OCSP to check the validity of the server certificate. If set to 1 or 2, the component will first obtain the OCSP URL from the server certificate's OCSP extension. The component will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the component raises an exception.

When set to 0 (default) the component will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

This minimum cipher strength largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.

Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.

The enabled cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the component will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Example values when SSLProvider is set to Platform: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); Possible values when SSLProvider is set to Platform include:
