ICharge Class

Properties   Methods   Events   Config Settings   Errors  

The ICharge class is used to authorize credit card transactions with any of the supported Internet Payment Gateways.

Syntax

class inpay.ICharge

Remarks

The ICharge class allows you to use multiple Internet Payment Gateways through one interface and one class. This allows for easy migration from one gateway to another, as well as quick integration into applications or web services.

The ICharge class allows your website to securely perform credit card transactions without the need to redirect to a third-party site. All transactions are accomplished through a secure HTTPS Post to any supported gateway. The secure response is received and then stored in the class's response properties. Any web site on a standard HTTP server or any stand-alone application can process transactions without the need for a secure server or third-party intervention.

The first thing you must do is select one of the many gateways supported by the ICharge class, and set up an account with that gateway vendor. Once you have an account set up with a valid (or test) login Id and password, you can use the ICharge class.

To begin, set the gateway property to the gateway you wish to use. If this gateway supports an alternate URL to send test transactions to, set the gateway_url at this time.

Next, set the merchant_login (and for some gateways the merchant_password). These are supplied by your gateway vendor when you set up an account.

Now you are ready to process transactions. For each transaction, you must set the card_number, card_exp_month, card_exp_year, and transaction_amount properties. Most gateways will also require additional properties, such as customer_address, customer_first_name, customer_last_name, invoice_number, etc. Any additional required properties are listed in the gateway property description.

Once these properties are set, you may run validity checks on the card data with the avs_only method, or simply authorize the transaction with the sale method. If your gateway supports it, you may also Void transactions that have not yet gone to settlement with the void_transaction method. Transactions that have already been settled may be refunded with the credit method. Please note that some gateways use the credit method for both voids and credits. See the transaction methods for more information.

The following gateways are supported by the ICharge class:

""

Remarks

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 card_cvv_data 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, card_cvv_presence will be automatically set to cvpProvided. If set to empty string (""), card_cvv_presence will be automatically set to cvpNotProvided.

card_cvv_presence Property

Syntax

def get_response_approved() -> bool: ...

response_approved = property(get_response_approved, None)

Default Value

FALSE

Remarks

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 response_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.

This property is read-only.

response_approved_amount Property

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.

This property is read-only.

ssl_server_cert_encoded Property

The certificate (PEM/Base64 encoded).

Syntax

def get_ssl_server_cert_encoded() -> bytes: ...

ssl_server_cert_encoded = property(get_ssl_server_cert_encoded, None)

Default Value

""

Remarks

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

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

This property is read-only.

test_mode Property

Turns test mode on and off for transactions sent to the current Gateway .

Syntax

def get_test_mode() -> bool: ...
def set_test_mode(value: bool) -> None: ...

test_mode = property(get_test_mode, set_test_mode)

Default Value

FALSE

Remarks

You can use this property to set a test mode flag that will be sent in an authorization request. Not all gateways support test modes. If you set the test_mode property to True and the current gateway does not support it, the class will fails with an error.

timeout Property

A timeout for the class.

Syntax

def get_timeout() -> int: ...
def set_timeout(value: int) -> None: ...

timeout = property(get_timeout, set_timeout)

Default Value

30

Remarks

If timeout is set to a positive value, and an operation cannot be completed immediately, the class will retry the operation for a maximum of timeout seconds.

The default value for timeout is 30 (seconds).

transaction_amount Property

Purchase amount for an authorization transaction.

Syntax

def get_transaction_amount() -> str: ...
def set_transaction_amount(value: str) -> None: ...

transaction_amount = property(get_transaction_amount, set_transaction_amount)

Default Value

""

Remarks

This field contains the transaction amount to be authorized. Gateways may have differing requirements for how the TransactionAmount should be formatted, so refer to the ICharge Gateway Setup page for details on the gateway you are using.

transaction_desc Property

Description of goods purchased.

Syntax

def get_transaction_desc() -> str: ...
def set_transaction_desc(value: str) -> None: ...

transaction_desc = property(get_transaction_desc, set_transaction_desc)

Default Value

""

Remarks

This field contains a description of the goods or services being purchased. Please see the "ICharge Gateway Setup and Required Properties" page to determine if this is a required or optional field for the gateway you are using.

transaction_id Property

Merchant-generated transaction Id used for all transactions.

Syntax

def get_transaction_id() -> str: ...
def set_transaction_id(value: str) -> None: ...

transaction_id = property(get_transaction_id, set_transaction_id)

Default Value

""

Remarks

This property is used to send a merchant-generated transaction id to the gateway, if the gateway supports that feature.

add_special_field Method

Adds a special field name and the corresponding value.

Syntax

def add_special_field(name: str, value: str) -> None: ...

Remarks

Please refer to the special_field_name and special_field_value properties for more information on form variables and how they are managed.

auth_only Method

Initiates an authorization-only request transaction.

Syntax

def auth_only() -> None: ...

Remarks

This method sends an authorization-only request to the specified gateway. This transaction is not added to the current open batch, and must be completed later with the capture method (you may use the sale method if you wish to authorize and capture in one step).

Note: If the gateway does not support this method, the class will fails with an error.

avs_only Method

Used to check the validity of the card without authorizing funds.

Syntax

def avs_only() -> None: ...

Remarks

This method can be used if you wish to perform fraud (AVS and CVV) checks on a card, but don't actually wish to charge the customer. This is useful for pre-ordering an item that has not yet been released or is currently back- ordered. The card information is validated by the merchant, and when the item is later in stock and ships to the customer, an sale transaction can be performed.

Note: If the gateway does not support this method, the class will fails with an error.

capture Method

Captures a previously authorized transaction.

Syntax

def capture(transaction_id: str, capture_amount: str) -> None: ...

Remarks

This method captures a transaction that has been previously authorized with the auth_only method. The TransactionId parameter indicates to the gateway which transaction is to be captured, and should contain the response_transaction_id from the original transaction. The CaptureAmount parameter is the value to be captured from the customer's credit card, and can be different from the authorized amount.

Please see the gateway information in the table of contents to determine if your gateway supports Capture transactions.

The LinkPoint and PSIGateXML gateways require you send the response_invoice_number rather than the response_transaction_id.

The SecurePay gateway does not require the TransactionId for captures. Instead, you must send the response_approval_code returned from the original response in the auth_code property.

The MyVirtualMerchant and Converge gateways do not require the TransactionId for captures. Instead, you must send the response_approval_code returned from the original response in the auth_code property. Note that there is a new capture transaction type available for these gateways. To use the new transaction type, set the MyVirtualMerchantTransactionType to "CCCOMPLETE" and call capture like normal. When using this transaction type, TransactionId is required and response_approval_code is not applicable.

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, 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

Credits a customer's card.

Syntax

def credit() -> None: ...

Remarks

This method credits a customer's card specified via card. This type of transaction is NOT based on previous transaction. Some gateways refer to these as "Open" or "Blind" Credits.

transaction_amount is used to specify the amount you wish to return to the customer's card.

Please see the gateway information in the table of contents to determine if your gateway supports Credit transactions.

do_events Method

This method processes events from the internal message queue.

Syntax

def do_events() -> None: ...

Remarks

When do_events is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

force Method

Used when authorization cannot be obtained online.

Syntax

def force(voice_auth_code: str) -> None: ...

Remarks

This method is used when the response to a sale or auth_only request indicates that voice authorization is required. The merchant then telephones the call center and receives a voice authorization code. Calling the force method with this code in the VoiceAuthCode parameter will complete the transaction.

Note: If the gateway does not support this method, the class will fails with an error.

get_response_var Method

Parses additional information out of the response.

Syntax

def get_response_var(name: str) -> str: ...

Remarks

Due to the fact that this class supports so many gateways, only the most commonly used response variables are parsed into the response properties. Any additional response information contained within the response_data may be retrieved with this get_response_var method. There are three formats for the response_data returned by the gateways this class supports: Name/value pairs, delimited list, or XML. The value you pass in the Name parameter changes based on these formats, as detailed below:

If the response_data property contains name/value pairs, pass the name in the Name parameter and this method will return the value. For instance, if response_data contains "ResponseCode=00&FraudScore=53&ApprovalCode=123456&...", calling GetResponseVar("FraudScore") will return "53".

However, if response_data contains a delimited list, pass the index of the field you wish to receive. For instance, if response_data contains "00|53|123456|...", calling GetResponseVar("1") will return "53".

Finally, if response_data contains XML, pass the xpath to the value you wish to receive. For instance, if response_data contains "<Response><Code>00</Code><FraudScore>53</FraudScore><ApprovalCode>123456</ApprovalCode></Response>", calling GetResponseVar("/Response/FraudScore") will return "53".

interrupt Method

Interrupts the current action.

Syntax

def interrupt() -> None: ...

Remarks

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

refund Method

Refunds a previously captured transaction.

Syntax

def refund(transaction_id: str, refund_amount: str) -> None: ...

Remarks

This method refunds a transaction that has already been captured, or settled. If the transaction is still outstanding use the void_transaction method instead. The TransactionId parameter indicates to the gateway which transaction is to be refunded, and should contain the response_transaction_id from the original transaction. The RefundAmount parameter is the value to be refunded back to the customer, and can be all or part of the original transaction_amount

Please see the gateway information in the table of contents to determine if your gateway supports Refund transactions.

The gw3DSI gateway requires the following additional fields for Refund transactions:

class.AddSpecialField "UserId", "my 3DSI-assigned UserId" '(Different than merchant_login) class.MerchantPassword = "my 3DSI-assigned Pwd"

The LinkPoint and PSIGateXML gateways require you send the response_invoice_number rather than the response_transaction_id.

reset Method

Clears all properties to their default values.

Syntax

def reset() -> None: ...

Remarks

This method clears all properties to their default values and returns the component to its default state.

reset_special_fields Method

Resets all special fields to the default settings.

Syntax

def reset_special_fields() -> None: ...

Remarks

This function resets all special gateway configuration fields to the default settings for the specified gateway.

Please refer to the special_field_name and special_field_value properties for more information on form variables and how they are managed.

sale Method

Initiates an Sale transaction (authorization and capture).

Syntax

def sale() -> None: ...

Remarks

Sends a basic sale transaction to the gateway. This transaction decrements the cardholder's open-to-buy funds for the transaction_amount, and the transaction is automatically added to the current open batch.

void_transaction Method

Voids a previously authorized transaction.

Syntax

def void_transaction(transaction_id: str) -> None: ...

Remarks

This method voids a transaction that has been previously authorized, but which has not yet gone to settlement, or been "captured". The TransactionId parameter indicates to the gateway which transaction is to be voided, and should contain the response_transaction_id from the original transaction.

Please see the gateway information in the table of contents to determine if your gateway supports Void transactions.

To cancel a transaction which has already been captured, use the credit method.

The LinkPoint gateway requires you send the response_invoice_number rather than the response_transaction_id.

For the PSIGateXML gateway, send the response_transaction_id as normal.

For the Heartland gateway, a reversal transaction will be sent when a transaction_amount is specified. Otherwise a void transaction will be sent.

on_error Event

Information about errors during data delivery.

Syntax

class IChargeErrorEventParams(object):
  @property
  def error_code() -> int: ...

  @property
  def description() -> str: ...

# In class ICharge:
@property
def on_error() -> Callable[[IChargeErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[IChargeErrorEventParams], None]) -> None: ...

Remarks

The on_error event is fired in case of exceptional conditions during message processing.

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

on_ssl_server_authentication Event

Fired after the server presents its certificate to the client.

Syntax

class IChargeSSLServerAuthenticationEventParams(object):
  @property
  def cert_encoded() -> bytes: ...

  @property
  def cert_subject() -> str: ...

  @property
  def cert_issuer() -> str: ...

  @property
  def status() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class ICharge:
@property
def on_ssl_server_authentication() -> Callable[[IChargeSSLServerAuthenticationEventParams], None]: ...
@on_ssl_server_authentication.setter
def on_ssl_server_authentication(event_hook: Callable[[IChargeSSLServerAuthenticationEventParams], None]) -> None: ...

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.

on_ssl_status Event

Fired when secure connection progress messages are available.

Syntax

class IChargeSSLStatusEventParams(object):
  @property
  def message() -> str: ...

# In class ICharge:
@property
def on_ssl_status() -> Callable[[IChargeSSLStatusEventParams], None]: ...
@on_ssl_status.setter
def on_ssl_status(event_hook: Callable[[IChargeSSLStatusEventParams], None]) -> None: ...

Remarks

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