I just did this in C# Mike. First things first; the things that bit me...
1. Order your SSL certificate.
2. Get your merchant account.
3. Choose a payment gateway.
Also stay away from Pay Pal Pro. This is a new pay pal offering that lets you
do real time credit card transaction without the merchant account or gateway
via web services. Sounds good on paper but the docs are terrible, service and
help non-existent. This will be good once it matures.
I used Authorize.Net for a gateway and they provided me with an API and
tutorial. There isn't a "Script" to download because it is different depending
on the different gateways. Once you choose one you will have a better
understanding of the task. I would recommend Verisign and Authorize.net. As
for credit card validation prior to sending it to the gateway...
These are the two things I use to do Credit Card Validation... Keep in mind
this means it CAN be a valid credit card number not that it is. Also This
isn't my code and I want to give credit where credit is due... but I don't know
who wrote it; I have been using it for a while and made some mods to it.

Subject: [AspNetAnyQuestionIsOk] Credit Card Processing
Credit card processing in asp.net in Vb.net language. I have seen most
websites do this and take an order via a form and then process it. Is there
a script out there that does this and a place to learn how this all works?
Thanks.
Mike
