Ah! Ok, well I'll keep you posted if I figure something out! Please do the same if you don't mind?
I will tell you this -- the API is a pain in the a**. They give you a 600 page API Reference pdf file that has C++ and Java COM objects to deal with, then you're expected to figure most of it out and program the API interface (they give some XML examples, but not how to deal with them). No good referrences to PHP, HTML, or ASP.
I'm beginning to thind we should have went with a different gateway (easier implementation), but the boss saw the low price and didn't investigate into the integration difficulties!
Oh, well, I'll keep researching and will post if I make any breakthroughs.
Thanks again!
