First Data Payment Gateway

We need to add a form on our site that submits the customers credit card/address etc. to the First Data Payment Gateway and return approval / Error or Denied response plus all the transaction data First Data replays with. We already have all the customer information in a database we will populate the classic asp from with this data you will need to use test data to validate your code. From there the form will be submitted to a 2nd page on the site that will send the data/information to First Data and wait for a reply, once a reply is receives back display the information that First Data sends back. We will process the data from there. The page that send the data/information to First Data can be in Classic ASP, ASP.NET or XML. This is not a form hosted by First Data this form will reside on our server. Prefer to work with someone that has done work with First Data before. [login to view URL] Thanks.
