Publisher review:CyberCash Payment Module allows you to continue using CyberCash through VeriSign instead of having to switch-over to their more expensive Payflow Pro. No one had developed a CyberCash module, and I really needed one, so I decided to tackle it myself. I'm glad I can give something back to the osCommerce community. For all of you CyberCash users out there, I hope this allows you to continue using CyberCash through VeriSign instead of having to switch-over to their more expensive Payflow Pro. I developed this against osCommerce v2.2 MS2 and an unmodified installation of CyberCash MCK v3.2. It is assumed that your CyberCash MCK installation is functional using CyberCash's included HTML test page. Mainly, be sure your CYBERCASH_ID, HASH_SECRET, and MERCHANT_KEY are all entered into the "merchant_conf" file of your CyberCash MCK installation. If so, then you should have no problems.
CyberCash Payment Module is a PHP script for osCommerce Addons scripts design by David Cannon.
It runs on following operating system: Windows / Linux / BSD.
