The FDMSDebit component is an advanced tool used to authorize debit cards in a Retail environment, where the customer is purchasing products or services in person. This component makes authorizing debit card transactions with a customer PIN very easy.

Syntax

TibcFDMSDebit

Remarks

This component connects to the First Data Merchant Services (FDMS) processor, by way of the Datawire VXN transaction transport network. Transactions originating with these components go through Datawire, to the FDMS processor where the transaction is authorized. The result is then returned back through Datawire and received by the component. This component can be integrated into web pages or stand-alone Point Of Sale applications. Because all SSL communications are handled inside the component, any application or web page can be deployed without the need for expensive dedicated SSL servers.

The FDMSDebit component makes authorizing debit transactions (where the customer is present and inputs his PIN number) very easy by adding an additional layer of abstraction between the programmer and the protocol. There is no need to deal with raw sockets, TLS/SSL handshakes, or data packet formatting. The steps to setting up the component and sending transactions are outlined below:

First, you must register and activate your account with Datawire. Datawire will provide you with a MerchantNumber and MerchantTerminalNumber, but you'll need to use the FDMSRegister component to activate the merchant and receive a DatawireId. Once you acquire the DatawireId and receive your transaction URLs through Service Discovery, you may begin to authorize transactions.

To authorize a credit card, set the MerchantNumber and MerchantTerminalNumber with the values supplied by FDMS and Datawire, and the DatawireId with the value retrieved by the FDMSRegister component after activating your merchant account. Set the URL property with one of the URLs you retrieved during Service Discovery.

FDMSDebit.MerchantNumber = "000000999990" //Supplied by FDMS/Datawire FDMSDebit.MerchantTerminalNumber = "555555" //Supplied by FDMS/Datawire FDMSDebit.DatawireId = "0000B47FFFFFFFFFFFFF" //Retrieved with the FDMSRegister component. FDMSDebit.URL = "https://staging1.datawire.net/sd/"; //Retrieved with the FDMSRegister component. Next, set properties that contain details about the transaction. The TransactionNumber should be incremented for every transaction you send. The TransactionAmount must be set, and it should contain the amount to be charged, with an implied decimal point (ie: $1.00 is "100"). There is no IndustryType property for the FDMSDebit component. The format of the transmitted data does not change for different industry types. Do note that the FDMSDebit component can only be used in a retail environment, where the card and customer are present. The card must be swiped and track2 data must be sent in CardMagneticStripe property - debit transactions may NOT be manually-keyed. Debit transactions also require the customer to input his PIN into a certified PIN Pad device, which will return an encrypted PIN and a Key Sequence Number to the merchant. These must be submitted with the transaction in the EncryptedPIN and KSN properties. A unique ReceiptNumber used to identify the transaction on the merchant's system is also required for all transactions. This number must also be printed on the customer's receipt.

Debit sale transactions differ from credit card authorizations in that they are real-time -- Funds are immediately removed from (or added to) the customer's bank account. However, even though debit transactions are real-time, FDMS requires they be settled at the end of the day just like credit card transactions.

The example below shows how to submit a simple debit sale transaction. FDMSDebit.TransactionNumber = 1 FDMSDebit.TransactionAmount = "2500" FDMSDebit.CardMagneticStripe = "4017779999999011=12041200000000001" FDMSDebit.CardEntryDataSource = edsTrack1 FDMSDebit.EncryptedPIN = "37B8091E37FA1773" FDMSDebit.KSN = "8765432109003000018" FDMSDebit.ReceiptNumber = "123456" FDMSDebit.Sale

When the component receives a response, the result of the authorization will be available in several Response properties. The ResponseDatawireStatus and ResponseDatawireReturnCode indicate whether any errors occurred while passing the transaction through the Datawire VXN system. These two properties alone do not indicate a successful transaction, they only tell whether or not there were any problems transporting the authorization request and response through the Datawire system. If the transaction was successfully authorized by FDMS, then the ResponseCaptureFlag will be True, and the ResponseApprovalCode will contain an approval code that beings with "AP". (or "AL" for components that support partially-approved/split-tender transactions).

Once an authorization request is approved, the money in the customer's account is blocked and tagged for the merchant. This transaction must go through the Batch Settlement process in order for the blocked money to be transferred to the merchant account. This is done by passing the XML aggregate returned from the GetDetailAggregate method to the FDMSSettle component. Usually, a Batch Settlement of all authorized transactions is done at the end of each business day.

Important Note: You must ping your list of service provider URLs and update the URL property to the service provider with the shortest response time every 100 transactions, as well as when your application initially starts. This is not a normal ICMP ping - to determine the fastest transaction URL you must use the special Ping method inside the FDMSRegister component. (You may update your list of service provider URLs with the FDMSRegister component's ServiceDiscovery method).

CardIsEncrypted Property (FDMSDebit Component)

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

Syntax

__property bool CardIsEncrypted = { read=FCardIsEncrypted, write=FSetCardIsEncrypted };

Default Value

false

Remarks

Determines whether data set to the CardNumber or CardMagneticStripe fields is validated.

By default, when the CardNumber or CardMagneticStripe fields are set, the value will be validated and normalized. For instance, "4444-33332222 1111" will be normalized as "4444333322221111" and CardMagneticStripe data will be parsed for the track specified by CardEntryDataSource. 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 CardNumber or CardMagneticStripe 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.

This property is not available at design time.

Data Type

Boolean

CardMagneticStripe Property (FDMSDebit Component)

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

Syntax

__property String CardMagneticStripe = { read=FCardMagneticStripe, write=FSetCardMagneticStripe };

Default Value

""

Remarks

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

If CardEntryDataSource 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 CardEntryDataSource property to indicate which track you are sending.

The following example shows how to set the CardMagneticStripe and CardEntryDataSource 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.

This property is not available at design time.

Data Type

String

Customer's credit card number for the transaction.

Syntax

__property String CardNumber = { read=FCardNumber, write=FSetCardNumber };

Default Value

""

Remarks

Customer's credit card number for the transaction.

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

This property is not available at design time.

Data Type

String

CashBack Property (FDMSDebit Component)

Optional cash back amount to return to the customer.

Syntax

__property String CashBack = { read=FCashBack, write=FSetCashBack };

Default Value

""

Remarks

This amount is to be presented with an implied decimal point. For example, US $10.00 must be represented as 1000, and $0.10 is likewise simply 10. The largest possible CashBack amount is "99999", yielding a maximum US dollar amount of $999.99. This field may not contain a negative number.

For cash back transactions, the TransactionAmount must contain the sum total of the purchase amount PLUS the CashBack amount. If the purchase is for $10 and the customer requests $20 cash back, CashBack should be set to "2000" and TransactionAmount must contain "3000".

Note that only US currency is supported for debit transactions.

Data Type

String

DatawireId Property (FDMSDebit Component)

Identifies the merchant to the Datawire System.

Syntax

__property String DatawireId = { read=FDatawireId, write=FSetDatawireId };

Default Value

""

Remarks

The Datawire Id is a unique customer identifier generated by Datawire and returned to the client after successfully registering the merchant (using the FDMSRegister component). This Id (which is sent in all subsequent transactions) allows a transaction, to pass through the Datawire system and be correctly routed to the FDMS Payment processor.

The maximum length for this property is 32 characters.

Data Type

String

EncryptedPIN Property (FDMSDebit Component)

DUKPT DES encrypted pin block, retrieved from a PIN pad.

Syntax

__property String EncryptedPIN = { read=FEncryptedPIN, write=FSetEncryptedPIN };

Default Value

""

Remarks

A 16-byte encrypted PIN and associated KSN are required for all debit Sale and Credit transactions. These values must be retrieved from a certified DUKPT DES pin pad device.

The EncryptedPIN and KSN are not required for ReverseLastTransaction transactions.

The following code snippet shows how to send a simple debit sale transaction with all required properties. FDMSDebit1.MerchantNumber = "YOURNUMBER" FDMSDebit1.MerchantTerminalNumber = "YOURTERMID" FDMSDebit1.DatawireId = "YOURDID" FDMSDebit1.URL = "https://staging1.datawire.net/sd"; // test server FDMSDebit1.TransactionNumber = 4; FDMSDebit1.TransactionAmount = "100"; FDMSDebit1.Card.EntryDataSource = edsTrack2; FDMSDebit1.Card.MagneticStripe = "9876543210012341234=12041200000001"; // (pin 1234) FDMSDebit1.EncryptedPIN = "0082943935BA205D"; FDMSDebit1.KSN = "8765432109003000012"; FDMSDebit1.ReceiptNumber = "123456"; FDMSDebit1.Sale(); If the transaction is successful, the ResponseApprovalCode will start with "AP", and the ResponseCaptureFlag will be true. Even though debit transactions are on-line transactions, it is still necessary to settle them with First Data. The following example shows how to send a simple settlement. The first thing to do is to set up the FDMSSettle component's properties with the same information used for the debit sale: FDMSSettle1.MerchantNumber = FDMSDebit1.MerchantNumber; FDMSSettle1.MerchantTerminalNumber = FDMSDebit1.MerchantTerminalNumber; FDMSSettle1.DatawireId = FDMSDebit1.DatawireId; FDMSSettle1.URL = FDMSDebit1.URL; FDMSSettle1.MerchantServiceNumber = "8001234567"; FDMSSettle1.BatchSequenceNumber = "101"; FDMSSettle1.IndustryType = itRetail; Then all that needs to be done is add the detail record from the debit sale to the settlement component and call the SendSettlement method. FDMSSettle1.DetailRecords.Add(new FDMSRecordType(FDMSDebit1.GetDetailAggregate()); FDMSSettle1.SendSettlement(); Note that in a live system you would store detail records in a database and send multiple records in a single batch at the end of the business day.

Data Type

String

FDMSPlatform Property (FDMSDebit Component)

Specifies the FDMS platform that the transactions will be processed on.

Syntax

__property TibcFDMSDebitFDMSPlatforms FDMSPlatform = { read=FFDMSPlatform, write=FSetFDMSPlatform };

enum TibcFDMSDebitFDMSPlatforms {
  fpNorth=0,
  fpNashville=1

Remarks

A 19 or 20-byte Key Sequence Number (KSN) and associated EncryptedPIN are required for all debit Sale and Credit transactions. These values must be retrieved from a certified DUKPT DES pin pad device. A 20-byte Key Sequence Number consists of a 1-byte pad character ('F'), a 9-byte Base Derivation Key Id (BDK ID), a 5-byte device Id, and a 5-byte transaction counter. If this property is set with a Key Sequence Number less than 20 bytes in length, the component will pad it on the left with 'F' characters.

The EncryptedPIN and KSN are not required for ReverseLastTransaction transactions.

The following code snippet shows how to send a simple debit sale transaction with all required properties. FDMSDebit1.MerchantNumber = "YOURNUMBER" FDMSDebit1.MerchantTerminalNumber = "YOURTERMID" FDMSDebit1.DatawireId = "YOURDID" FDMSDebit1.URL = "https://staging1.datawire.net/sd"; // test server FDMSDebit1.TransactionNumber = 4; FDMSDebit1.TransactionAmount = "100"; FDMSDebit1.Card.EntryDataSource = edsTrack2; FDMSDebit1.Card.MagneticStripe = "9876543210012341234=12041200000001"; // (pin 1234) FDMSDebit1.EncryptedPIN = "0082943935BA205D"; FDMSDebit1.KSN = "8765432109003000012"; FDMSDebit1.ReceiptNumber = "123456"; FDMSDebit1.Sale(); If the transaction is successful, the ResponseApprovalCode will start with "AP", and the ResponseCaptureFlag will be true. Even though debit transactions are on-line transactions, it is still necessary to settle them with First Data. The following example shows how to send a simple settlement. The first thing to do is to set up the FDMSSettle component's properties with the same information used for the debit sale: FDMSSettle1.MerchantNumber = FDMSDebit1.MerchantNumber; FDMSSettle1.MerchantTerminalNumber = FDMSDebit1.MerchantTerminalNumber; FDMSSettle1.DatawireId = FDMSDebit1.DatawireId; FDMSSettle1.URL = FDMSDebit1.URL; FDMSSettle1.MerchantServiceNumber = "8001234567"; FDMSSettle1.BatchSequenceNumber = "101"; FDMSSettle1.IndustryType = itRetail; Then all that needs to be done is add the detail record from the debit sale to the settlement component and call the SendSettlement method. FDMSSettle1.DetailRecords.Add(new FDMSRecordType(FDMSDebit1.GetDetailAggregate()); FDMSSettle1.SendSettlement(); Note that in a live system you would store detail records in a database and send multiple records in a single batch at the end of the business day.

Default Value

""

Remarks

This property is required for Debit transaction clearing, and should contain a unique 6-digit trace number identifying the transaction. The merchant application should generate a unique number for each Debit or EBT transaction. If a Debit or EBT transaction is voided or reversed, the ReceiptNumber of the original transaction should be used. The receipt number must be passed to the FDMS Host on both the Debit/EBT authorization request and the batch settlement detail. It must also be printed on the customer receipt. Used such, this number satisfies Debit Network Provider requirements.

After an authorization request, the ResponseCaptureFlag will be set to True if the request was successfully processed. This indicates that you may send the transaction on for batch settlement using the FDMSSettle component. If this property is False you should consider the transaction as Declined, and it may not be settled.

This property is read-only.

Data Type

Boolean

ResponseDatawireReturnCode Property (FDMSDebit Component)

Contains an error code providing more details about the DatawireStatus received.

Syntax

__property String ResponseDatawireReturnCode = { read=FResponseDatawireReturnCode };

Default Value

""

Remarks

Contains an error code providing more details about the ResponseDatawireStatus received.

When a transaction is successfully passed from the application, through the Datawire system to the FDMS payment processor and back, the ResponseDatawireStatus will be "OK" and the ResponseDatawireReturnCode will be "000". These two properties have NO BEARING on the actual results of any transaction. Even though the transaction has successfully passed through the Datawire system, it can still fail to be processed successfully by FDMS. This property only indicates that the request reached FDMS, and that FDMS responded with some data.

The ResponseCaptureFlag and ResponseApprovalCode properties contain the actual transaction result that was returned by FDMS.

The following is a list of possible Datawire return codes:

This property is read-only.

Data Type

SSLAcceptServerCertEncoded Property (FDMSDebit Component)

This is the certificate (PEM/Base64 encoded).

Syntax

__property String SSLAcceptServerCertEncoded = { read=FSSLAcceptServerCertEncoded, write=FSetSSLAcceptServerCertEncoded };
__property DynamicArray<Byte> SSLAcceptServerCertEncodedB = { read=FSSLAcceptServerCertEncodedB, write=FSetSSLAcceptServerCertEncodedB };

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSLAcceptServerCertStore and SSLAcceptServerCertSubject properties also may be used to specify a certificate.

When SSLAcceptServerCertEncoded is set, a search is initiated in the current SSLAcceptServerCertStore for the private key of the certificate. If the key is found, SSLAcceptServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLAcceptServerCertSubject is set to an empty string.

This property is not available at design time.

Data Type

Byte Array

SSLCertEncoded Property (FDMSDebit Component)

This is the certificate (PEM/Base64 encoded).

Syntax

__property String SSLCertEncoded = { read=FSSLCertEncoded, write=FSetSSLCertEncoded };
__property DynamicArray<Byte> SSLCertEncodedB = { read=FSSLCertEncodedB, write=FSetSSLCertEncodedB };

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSLCertStore and SSLCertSubject properties also may be used to specify a certificate.

When SSLCertEncoded is set, a search is initiated in the current SSLCertStore for the private key of the certificate. If the key is found, SSLCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLCertSubject is set to an empty string.

This property is not available at design time.

Data Type

Byte Array

SSLCertStore Property (FDMSDebit Component)

This is the name of the certificate store for the client certificate.

Syntax

__property String SSLCertStore = { read=FSSLCertStore, write=FSetSSLCertStore };
__property DynamicArray<Byte> SSLCertStoreB = { read=FSSLCertStoreB, write=FSetSSLCertStoreB };

Default Value

"MY"

Remarks

This is the name of the certificate store for the client certificate.

The SSLCertStoreType property denotes the type of the certificate store specified by SSLCertStore. If the store is password protected, specify the password in SSLCertStorePassword.

SSLCertStore is used in conjunction with the SSLCertSubject property to specify client certificates. If SSLCertStore has a value, and SSLCertSubject or SSLCertEncoded is set, a search for a certificate is initiated. Please see the SSLCertSubject property for details.

Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

Data Type

Byte Array

SSLCertStorePassword Property (FDMSDebit Component)

If the type of certificate store requires a password, this property is used to specify the password needed to open the certificate store.

Syntax

__property String SSLCertStorePassword = { read=FSSLCertStorePassword, write=FSetSSLCertStorePassword };

Default Value

""

Remarks

If the type of certificate store requires a password, this property is used to specify the password needed to open the certificate store.

Data Type

String

SSLCertStoreType Property (FDMSDebit Component)

This is the type of certificate store for this certificate.

Syntax

__property TibcFDMSDebitSSLCertStoreTypes SSLCertStoreType = { read=FSSLCertStoreType, write=FSetSSLCertStoreType };

enum TibcFDMSDebitSSLCertStoreTypes {
  cstUser=0,
  cstMachine=1,

  cstSecurityKey=20,
  cstBCFKSFile=21,
  cstBCFKSBlob=22,
  cstPKCS11=23,
  cstAuto=99
};

Default Value

cstUser

Remarks

This is the type of certificate store for this certificate.

The component supports both public and private keys in a variety of formats. When the cstAuto value is used, the component will automatically determine the type. This property can take one of the following values:

Data Type

Integer

SSLCertSubject Property (FDMSDebit Component)

This is the subject of the certificate used for client authentication.

Syntax

__property String SSLCertSubject = { read=FSSLCertSubject, write=FSetSSLCertSubject };

Default Value

""

Remarks

This is the subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

If a field value contains a comma, it must be quoted.

Data Type

String

SSLProvider Property (FDMSDebit Component)

This specifies the SSL/TLS implementation to use.

Syntax

__property TibcFDMSDebitSSLProviders SSLProvider = { read=FSSLProvider, write=FSetSSLProvider };

enum TibcFDMSDebitSSLProviders {
  sslpAutomatic=0,
  sslpPlatform=1,
  sslpInternal=2
};

Default Value

sslpAutomatic

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the component will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

In most cases using the default value (Automatic) is recommended. The component will select a provider depending on the current platform.

When Automatic is selected the platform implementation is used by default. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used.

Data Type

Integer

SSLServerCertEncoded Property (FDMSDebit Component)

This is the certificate (PEM/Base64 encoded).

Syntax

__property String SSLServerCertEncoded = { read=FSSLServerCertEncoded };
__property DynamicArray<Byte> SSLServerCertEncodedB = { read=FSSLServerCertEncodedB };

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.

When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.

This property is read-only and not available at design time.

Data Type

Byte Array

Timeout Property (FDMSDebit Component)

A timeout for the component.

Syntax

__property int Timeout = { read=FTimeout, write=FSetTimeout };

Default Value

30

Remarks

If Timeout is set to a positive value, and an operation cannot be completed immediately, the component will return with an error after Timeout seconds.

The default value for Timeout is 30 (seconds).

Data Type

Integer

TransactionAmount Property (FDMSDebit Component)

Total amount for the debit transaction.

Syntax

__property String TransactionAmount = { read=FTransactionAmount, write=FSetTransactionAmount };

Default Value

""

Remarks

This property should contain the total amount to be removed from a debit card for a Sale, including any optional CashBack amount. (eg, for a sale for $10 with a cash back of $20 TransactionAmount must contain "3000"). The TransactionAmount also specifies the total amount to Credit back to a debit card.

This amount is to be presented with an implied decimal point. For example, US $10.00 must be represented as 1000, and $0.10 is likewise simply 10. The allowable number of significant digits as well as the positioning of any implied decimal point is dictated by the designated CurrencyCode configuration setting. In the United States (default), the number of allowable significant digits is seven. Thus the maximum TransactionAmount is "9999999", yielding a US dollar amount of $99,999.99. This field may not contain a negative number.

Data Type

String

TransactionNumber Property (FDMSDebit Component)

Uniquely identifies the transaction.

Syntax

__property String TransactionNumber = { read=FTransactionNumber, write=FSetTransactionNumber };

Default Value

""

Remarks

The TransactionNumber (otherwise known as the Client Reference Number, or ClientRef) uniquely identifies the packet sent by the application to the Datawire system. This parameter stores some unique token of information, and is used to match the response to the initial request sent. For example, the client application could use a static counter that is increased with the each executed request.

For all components except FDMSGiftCard the maximum length of this property is 14 alphanumeric characters.

The FDMS recommended format is "tttttttVnnnnrrr" where ttttttt is a 7 digit transaction id, V is a constant, and nnn is a 3 digit version number and rrr is a 3 digit revision number. The 6 digit version number is typically static but unique for an application (Example: Version 2.5 = tttttttV002500).

For the Rapid Connect platform, the 6 character version number should be your Project/TPPID value. The entire TransactionNumber must be unique within a 24 hour time period.

The FDMSGiftCard also passes this value to the FDMS Closed Loop Gift Card system as a transaction id, and therefore the following restrictions are enforced: The maximum length is 7 characters. If the first character is an 'X', the remaining characters must be in the range '0' through 'F', indicating a hexadecimal number. Otherwise the FDMS Closed Loop Gift Card system only allows digits in this property.

Data Type

String

URL Property (FDMSDebit Component)

Location of the Datawire server to which transactions are sent.

Syntax

__property String URL = { read=FURL, write=FSetURL };

Default Value

"https://staging1.datawire.net/sd/"

Remarks

This is the URL to which all authorization and settlement transactions are sent. This URL is acquired by using the FDMSRegister component. Once you Register and Activate the merchant using the FDMSRegister component, you may then do a Service Discovery. After sending a Service Discovery transaction, the Datawire system will return a list of transaction URLs. The URL from this list with the shortest round-trip transit time from a ping is the URL you should use here.

Note: By default, this property is populated with the Datawire Staging (test) server, and is not the correct URL to use in a production environment. In a production environment, this URL is supplied by the FDMSRegister component.

Data Type

String

Config Method (FDMSDebit Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Credit Method (FDMSDebit Component)

Submits a credit transaction, returning funds to a debit card.

Syntax

void __fastcall Credit();

Remarks

Debit card credit (return) transactions differ from credit card off-line credits in that they are real-time -- Funds are immediately added to the customer's bank account, instead of the funds transfer taking place several days after settlement. Debit card transactions also must use track2 data read from the card's magnetic stripe. Track1 data is not acceptable, and a debit card may not be manually keyed. The customer enters his or her PIN number into a certified PIN Pad device, and both an EncryptedPIN and KSN (Key Sequence Number) are returned from the pad to the merchant, and must be submitted in the Credit/Return transaction.

Even though debit transactions are real-time, FDMS requires they be settled at the end of the day just like credit card transactions.

Important Note: You must ping your list of service provider URLs and update the URL property to the service provider with the shortest response time every 100 transactions, as well as when your application initially starts. This is not a normal ICMP ping - to determine the fastest transaction URL you must use the special Ping method inside the FDMSRegister component. (You may update your list of service provider URLs with the FDMSRegister component's ServiceDiscovery method).

GetDetailAggregate Method (FDMSDebit Component)

Returns an aggregate containing details of this transaction, which is then used for settlement.

Syntax

String __fastcall GetDetailAggregate();

Remarks

This method returns an aggregate containing all of the required data to send a transaction to settlement. This aggregate must be passed to the FDMSSettle component's DetailAggregate array property in order to settle the transaction. If you wish to view or change any part of the aggregate (such as adding a gratuity or additional info for an Installment payment), you may use the FDMSDetailRecord component to do so.

Note: This method may only be called after a successful authorization. If the authorization was not successful (and the ResponseCaptureFlag is false) the method raises an exception.

An example of how this method is used is shown below:

FDMSRetail.AuthorizeTrack1() If (FDMSRetail.ResponseCaptureFlag = True) Then FDMSSettle.DetailRecordCount = FDMSSettle.DetailRecordCount + 1 FDMSSettle.DetailRecordsAggregate[FDMSSettle.DetailRecordCount - 1] = FDMSRetail.GetDetailAggregate() End If

Interrupt Method (FDMSDebit Component)

Interrupts the current action.

Syntax

void __fastcall Interrupt();

Remarks

This method interrupts any processing that the component is currently executing.

Reset Method (FDMSDebit Component)

Clears all properties to their default values.

Syntax

void __fastcall Reset();

Remarks

This method clears all properties to their default values.

ReverseLastTransaction Method (FDMSDebit Component)

Used to reverse/void a previous transaction.

Syntax

void __fastcall ReverseLastTransaction();

Remarks

This method is used to reverse a previous transaction in the case a response was not received from the host or to void a previous Sale or Credit transaction.

A Timeout Reversal is needed when a terminal initiates a debit transaction (Sale or Credit) to the FDMS host, but the host fails to send a response back to the terminal for any reason. If a transaction times out or you receive a network connectivity error, you should immediately call ReverseLastTransaction. In this situation you don't know whether the host received the request and the response back to you was lost, or if the host ever received the request at all. Therefore the ReverseLastTransaction method can used to reverse the last transaction sent by this component. You must not change any properties or call any other methods (including Reset), as ReverseLastTransaction operates based on the current state of the component.

First Data will always send an ResponseApprovalCode of "AP888888" or "AP868686" on a reversal response, and the ResponseCaptureFlag value will be False. First Data does not check whether the original transaction occurred or not.

If you do not receive a response to the reversal (eg, it also times out), you must continue to call ReverseLastTransaction until you do receive a response.

Note: A Debit Reversal must not be used by the merchant as a way to credit a customer for returned merchandise.

Important Note: You must ping your list of service provider URLs and update the URL property to the service provider with the shortest response time every 100 transactions, as well as when your application initially starts. This is not a normal ICMP ping - to determine the fastest transaction URL you must use the special Ping method inside the FDMSRegister component. (You may update your list of service provider URLs with the FDMSRegister component's ServiceDiscovery method).

Sale Method (FDMSDebit Component)

Submits a sale transaction for a debit card.

Syntax

void __fastcall Sale();

Remarks

Debit sale transactions differ from credit card authorizations in that they are real-time -- Funds are immediately removed from the customer's bank account. Debit card transactions also must use track2 data read from the card's magnetic stripe. Track1 data is not acceptable, and a debit card may not be manually keyed. The customer enters his or her PIN number into a certified PIN Pad device, and both an EncryptedPIN and KSN (Key Sequence Number) are returned from the pad to the merchant, and must be submitted in the Sale transaction.

Even though debit transactions are real-time, FDMS requires they be settled at the end of the day just like credit card transactions.

Important Note: You must ping your list of service provider URLs and update the URL property to the service provider with the shortest response time every 100 transactions, as well as when your application initially starts. This is not a normal ICMP ping - to determine the fastest transaction URL you must use the special Ping method inside the FDMSRegister component. (You may update your list of service provider URLs with the FDMSRegister component's ServiceDiscovery method).

VoidTransaction Method (FDMSDebit Component)

Used to void a debit sale or credit transaction.

Syntax

void __fastcall VoidTransaction();

Remarks

This method can be used to void a Sale or Credit transaction that was previously made using this component. A Debit Void is a specialized transaction that corrects the impact of an approved Financial Transaction (Sale or Credit) because an error was discovered in the transaction or the customer changed his or her mind. A Debit Void is not used by the merchant as a way to credit a customer for returned merchandise.

The ReceiptNumber, KSN, TransactionAmount, CashBack, TransactionNumber, and all Card properties must be identical to the values submitted in the original sale, and the ApprovalCode parameter should contain the ResponseApprovalCode received in the original Response.

First Data will always send an ResponseApprovalCode of "AP888888" or "AP868686" as a response to a debit void, regardless of whether the original transaction occurred or not.

Important Note: You must ping your list of service provider URLs and update the URL property to the service provider with the shortest response time every 100 transactions, as well as when your application initially starts. This is not a normal ICMP ping - to determine the fastest transaction URL you must use the special Ping method inside the FDMSRegister component. (You may update your list of service provider URLs with the FDMSRegister component's ServiceDiscovery method).

Connected Event (FDMSDebit Component)

This event is fired immediately after a connection completes (or fails).

Syntax

typedef struct {
  int StatusCode;
  String Description;
} TibcFDMSDebitConnectedEventParams;
typedef void __fastcall (__closure *TibcFDMSDebitConnectedEvent)(System::TObject* Sender, TibcFDMSDebitConnectedEventParams *e);
__property TibcFDMSDebitConnectedEvent OnConnected = { read=FOnConnected, write=FOnConnected };

Remarks

If the connection is made normally, StatusCode is 0 and Description is "OK".

If the connection fails, StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error.

Please refer to the Error Codes section for more information.

DataPacketIn Event (FDMSDebit Component)

Fired when receiving a data packet from the transaction server.

Syntax

typedef struct {
  String DataPacket;
  DynamicArray<Byte> DataPacketB;
} TibcFDMSDebitDataPacketInEventParams;
typedef void __fastcall (__closure *TibcFDMSDebitDataPacketInEvent)(System::TObject* Sender, TibcFDMSDebitDataPacketInEventParams *e);
__property TibcFDMSDebitDataPacketInEvent OnDataPacketIn = { read=FOnDataPacketIn, write=FOnDataPacketIn };

Remarks

This event fires when a packet is received. The entire data packet (including all framing and error detection characters) is contained in the parameter "DataPacket". This parameter may be inspected for advanced troubleshooting, or to extract additional response properties beyond the scope of this component.

DataPacketOut Event (FDMSDebit Component)

Fired when sending a data packet to the transaction server.

Syntax

typedef struct {
  String DataPacket;
  DynamicArray<Byte> DataPacketB;
} TibcFDMSDebitDataPacketOutEventParams;
typedef void __fastcall (__closure *TibcFDMSDebitDataPacketOutEvent)(System::TObject* Sender, TibcFDMSDebitDataPacketOutEventParams *e);
__property TibcFDMSDebitDataPacketOutEvent OnDataPacketOut = { read=FOnDataPacketOut, write=FOnDataPacketOut };

Remarks

This event fires right before each data packet is sent. The entire data packet (including all framing and error detection characters) is contained in the parameter "DataPacket". This parameter may be inspected for advanced troubleshooting, or may be modified to support additional features beyond the scope of this component.

Disconnected Event (FDMSDebit Component)

This event is fired when a connection is closed.

Syntax

typedef struct {
  int StatusCode;
  String Description;
} TibcFDMSDebitDisconnectedEventParams;
typedef void __fastcall (__closure *TibcFDMSDebitDisconnectedEvent)(System::TObject* Sender, TibcFDMSDebitDisconnectedEventParams *e);
__property TibcFDMSDebitDisconnectedEvent OnDisconnected = { read=FOnDisconnected, write=FOnDisconnected };

Remarks

If the connection is broken normally, StatusCode is 0 and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by the Transmission Control Protocol (TCP/IP) subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error.

Please refer to the Error Codes section for more information.

Error Event (FDMSDebit Component)

Fired when information is available about errors during data delivery.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TibcFDMSDebitErrorEventParams;
typedef void __fastcall (__closure *TibcFDMSDebitErrorEvent)(System::TObject* Sender, TibcFDMSDebitErrorEventParams *e);
__property TibcFDMSDebitErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

SSLServerAuthentication Event (FDMSDebit Component)

Fired after the server presents its certificate to the client.

Syntax

typedef struct {
  String CertEncoded;
  DynamicArray<Byte> CertEncodedB;
  String CertSubject;
  String CertIssuer;
  String Status;
  bool Accept;
} TibcFDMSDebitSSLServerAuthenticationEventParams;
typedef void __fastcall (__closure *TibcFDMSDebitSSLServerAuthenticationEvent)(System::TObject* Sender, TibcFDMSDebitSSLServerAuthenticationEventParams *e);
__property TibcFDMSDebitSSLServerAuthenticationEvent OnSSLServerAuthentication = { read=FOnSSLServerAuthentication, write=FOnSSLServerAuthentication };

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (FDMSDebit Component)

Fired when secure connection progress messages are available.

Syntax

typedef struct {
  String Message;
} TibcFDMSDebitSSLStatusEventParams;
typedef void __fastcall (__closure *TibcFDMSDebitSSLStatusEvent)(System::TObject* Sender, TibcFDMSDebitSSLStatusEventParams *e);
__property TibcFDMSDebitSSLStatusEvent OnSSLStatus = { read=FOnSSLStatus, write=FOnSSLStatus };

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

Status Event (FDMSDebit Component)

Shows the progress of the FDMS/Datawire connection.

Syntax

typedef struct {
  String Message;
} TibcFDMSDebitStatusEventParams;
typedef void __fastcall (__closure *TibcFDMSDebitStatusEvent)(System::TObject* Sender, TibcFDMSDebitStatusEventParams *e);
__property TibcFDMSDebitStatusEvent OnStatus = { read=FOnStatus, write=FOnStatus };

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.
