====== Developers Guide ======

===== Introduction to Support Wiki =====

The USAePay Wiki provides a wealth of documentation for developers, merchant and resellers wishing to integrate their website,  pos application or third party software. 



  - Developing a payment processing application is a careful and tedious task. Merchant Services requires cooperation of [[http://www.usaepay.com/diagram.htm|several different entities]] such as a Merchant Bank, a Merchant Service Provider, a Processing Platform, the issuing Credit Card company, a Merchant and their developer, and of course us the USAePay gateway.
