First Data e4

The First Data Global Gateway e4℠ web service API is a web service that allows third-party applications to process transactions through the Global Gateway e4℠ system. The range of processing scenarios (Purchase, Refund, Pre-Authorization, etc.) enable flexible and powerful ways to implement custom business logic.

This module supports Authorize & Capture (Sale).

You will need a FirstData Global Gateway merchant account.
NOTE: If, you are using a previous version of FirstData (also known as Linkpoint), which needs a PEM file then, please use the gateway that is found within the Gold Cart package
