Can anyone recommend a payment gateway and processing company that functions similar to PayPal's Website Payments Pro? We cannot use it because we are barred from it for the time being.
I already set up my own cart and order system, so I just need to be able to send CC information to have it processed, e.g. via
curl. I looked at using Authorize.net AIM, which was promising, but they are only a payment gateway and do not do processing. Google Checkout's system seems very complicated, using XML. I just want to send some simple post parameters and get back authorization status.
