Config Method (Level2 Component)

Sets or retrieves a configuration setting.

Syntax

function Config(ConfigurationString: String): String;

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.

GetAggregate Method (Level2 Component)

Returns an aggregate containing level 2 details for a transaction.

Syntax

function GetAggregate(): String;

Remarks

This method returns an aggregate containing the level 2 data specified. This aggregate must be passed to the ICharge component's Level2Aggregate property in order for the level 2 data to be sent in the transaction. Each gateway has different requirements when processing level 2 transactions. Please refer to Level2 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()

Syntax

type TErrorEvent = procedure (
  Sender: TObject;
  ErrorCode: Integer;
  const Description: String
) of Object;

property OnError: TErrorEvent read FOnError write FOnError;

Remarks

The 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.

EPSpecialField Type

Additional name/value pairs which can be added to a transaction.

Remarks

This type contains a Name and Value which may contain any additional information you wish to send to your gateway that this component does not currently send. You must know the field name in the gateway integration guide available from your gateway. For instance, the code below shows how to add a customer IP Address for the Authorize.Net gateway:

ICharge1.SpecialFields.add(new EPSpecialField("x_customer_ip", "255.123.456.78"));
