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 directly from their shop.
The customer remains on your shop to complete the payment process thus giving them a seamless feel.

Two pieces of information must be provided when you submit a transaction via the Global Gateway e4℠ web service API, they are:

- Exact ID - also known as the Gateway ID, this value identifies the Merchant and Terminal under which the transaction is to be processed

- PASSWORD - authenticates the Global Gateway e4℠ web service API request, this value should not be exposed to the public

NOTE:
