This would be a plugin for VirtueMart to implement the [url removed, login to view] payment gateway and handl IPN notifications. Complexity is similar to PayPal Website Payments Standard.
Documentation for the payment button/redirect during checkout: [url removed, login to view]
Button image: [url removed, login to view]
IPN Documentation: [url removed, login to view]
The IPN handler should check for duplicate posts so payments aren't double-processed. Here is a plugin written for the system for another shopping cart you can use for reference also: [url removed, login to view]
If you have any questions I'll be glad to help any way I can.
