add_special_field Method
Adds a special field name and the corresponding value.
Syntax
def add_special_field(name: str, value: str) -> None: ...
Remarks
This method allows for specifying special fields for level 3 details at a transaction as well as a line item level. Typically level 3 details pertain to item details, however some gateways expose fields that are not item specific. This method allows you to specify these fields. Additionally you can specify item specific fields that aren't exposed via line_items. Please consult the gateways specifications to obtain available fields and their format.
Gateways implemented using XML may require the elements to be split into their own line item elements. In such a case, the specified Name value can be specified in the form "[index]:[name]" (where 'index' is the line_items index and 'name' is the name of the element you wish to add). The component will then parse the format and place line item data within the correct element in the request.
The following gateways are implemented using XML and support indexed special field values:
- gwBankOfAmerica (13)
- gwOrbital (23)
- gwSterling (45)
- gwLitle (63)
- gwPayTrace (70)
- gwDataCash (77)
- gwFirstDataE4 (80)
Please refer to the special_field_name and special_field_value properties for more information on form variables and how they are managed.
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.
get_aggregate Method
Returns an aggregate containing level 3 details for a transaction.
Syntax
def get_aggregate() -> str: ...
Remarks
This method returns an aggregate containing the level 3 data specified. This aggregate must be passed to the ICharge class's Level3Aggregate property in order for the level 3 data to be sent in the transaction. Each gateway has different requirements when processing level 3 transactions. Please refer to Level3 to identify which properties are required for the gateway you are implementing.
An example of how this method is used is shown below:
Level2.PONumber = "123456789"
Level2.ShipToZip = "27713"
Level2.TaxAmount = "1.23"
Level2.IsTaxExempt = false
ICharge.Level2Aggregate = Level2.GetAggregate()
Level3.LineItemCount = 2
Level3.LineItems[0].CommodityCode = "4900" // Books and printed materials
Level3.LineItems[0].Description = "Reference manual"
Level3.LineItems[0].DiscountAmount = "" // No discount
Level3.LineItems[0].ProductCode = "ISBN123456"
Level3.LineItems[0].Quantity = "2"
Level3.LineItems[0].TaxAmount = "60"
Level3.LineItems[0].TaxRate = "600" // 6.00 percent
Level3.LineItems[0].Total = "1060"
Level3.LineItems[0].UnitCost = "500"
Level3.LineItems[0].Units = "each"
Level3.LineItems.Add(new EPLineItem());
Level3.LineItems[1].CommodityCode = "4900"
Level3.LineItems[1].Description = "Quick Start manual"
Level3.LineItems[1].DiscountAmount = ""
Level3.LineItems[1].ProductCode = "ISBN654321"
Level3.LineItems[1].Quantity = "1"
Level3.LineItems[1].TaxAmount = "60"
Level3.LineItems[1].TaxRate = "600" // 6.00 percent
Level3.LineItems[1].Total = "1060"
Level3.LineItems[1].UnitCost = "1000"
Level3.LineItems[1].Units = "each"
on_error Event
Information about errors during data delivery.
Syntax
class Level3ErrorEventParams(object): @property def error_code() -> int: ... @property def description() -> str: ... # In class Level3: @property def on_error() -> Callable[[Level3ErrorEventParams], None]: ... @on_error.setter def on_error(event_hook: Callable[[Level3ErrorEventParams], 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.
Level3 Config Settings
The class accepts one or more of the following configuration settings. Configuration 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.Level3 Config Settings | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

UseInternalSecurityAPI:
Tells the class whether or not to use the system security libraries or an internal implementation.
When set to False, the class will use the system security libraries by default to perform cryptographic functions where applicable.
Setting this setting to True tells the class to use the internal implementation instead of using the system security libraries. On Windows, this setting is set to False by default. On Linux/macOS, this setting is set to True by default. To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section. |
