How To: Credit Card and ACH (e-check) integration in PHP

This is the fourth part in a series of postings on how to integrate credit card and ACH/E-check transactions into various systems. This installment demonstrates code used for processing payments (credit card and/or ACH) within a PHP application.

This was taken from the NELiX TransaX FleXport toolkit documentation. Credit card integration examples can be downloaded on the NELiX TransaX FleXport page.

Assumptions:
- Using NELiX TransaX Payment Gateway
- Communicating using NELiX TransaX Webservice
