I am working with a vendor, FirstData, and processing users credit card data using their secure gateway. The users fill out information on my webform, I use my own data validation in a code behind page using vb. My interface is done through a post method and I am successfull at all steps until their(FirstData) data fields are returned. The documentation doesn't give my much help other than to show the field names and their web setup/administration page says the following: "URL is CGI script". I have contacted their support and all they tell me is the output (fields) are returned and I must handle them. I am new to this side of things relating to cgi and reading fields in the webpage, so I feel like I am just spinning my wheels when it really shouldn't be that difficult. Can someone shed some light on how to read the URL cgi script and ge the page to appear?
