This extension now supports Order Transactions which allows for capturing, voiding, and refunding transactions directly within OpenCart!

This extension will allow your shopping cart to accept payments over the First Data Global Gateway e4 merchant gateway. The customer will be able to purchase with their credit/debit card directly on your secure site without ever leaving.

This extension uses the Web Service version of their API. This is the preferred API to use as it is the most feature filled and allows for more customization and reporting on the gateway.
