I've got an aMember php script installed on my webhost. I plan to use [url removed, login to view] as my payment gateway. Their checkout process uses perl. I need to get my aMember integrated with my vendor account at regnow somehow so when a customer orders from my site (they start with the aMember signup) that after a successful order with regnow, that the signup will finish on my amember script. If the order fails, their account they tried to make on my amember signup will not be made.
The aMember script already supports tons of payment gateways, but regnow is not one of them.
I am not sure if this will be possible, but I sure hope it is. I can provide a test order page so you can check out their order process and see if you can do it.
Example php script from regnow that shows some data that you may be able to use. http://www.regnow.com/html/help/vendor/httpordernotice.html
