Coldfusion SOAP XML Call to First Data Global Gateway e4 API

GOAL: Successfully submit and retrieve credit card transactions/response codes from Coldfusion to the First Data Global Gateway e4 gateway. We don't need anything more than a CFC that submits order form data to the gateway, receives the response codes for that submit, and prepares the response codes for further processing in a simple Coldfusion structure. Each card type must be tested (Visa, MC, Discover, AMEX, Diners Club), in addition to CVV and AVS filters (all of this is provided in a test environment with full, detailed specifications and examples. We have an existing solution in place using a Custom Tag and communicating with the Payflow Pro gateway. We'd like you to simply convert what we already have for use with the First Data Global Gateway e4 gateway. Complete First Data Global Gateway e4 gateway API reference documentation is available, as is our current Coldfusion code base for Payflow Pro. SEE ATTACHED DOCUMENT FOR REFERENCE For additional security, per the above document, we'd like to use the [login to view URL] endpoint along with the HMAC hash security calculation: [login to view URL] My server environment as it applies to this Project: CF10, WIN Server 2008 R2. I’d prefer to go the CFC route if possible providing we don’t have to re-work a bunch of our existing code. Regarding the SOAP envelope, I’d like to build it using raw XML and manual HTTP post instead of using CFInvoke or CreateObject( “webservice” ). This kind of SOAP handling gives us complete control over all aspects of both the request and the response and leaves no mystery as to how data types should be translated. We have an existing SOAP envelope available to model after if that helps your development. My expectations are to view and test the final code in our server environment prior to Project acceptance and payment (the way it used to work on [login to view URL]). First Data provides a fully functional test environment for your code, but you'll need to make these calls from your server and Coldfusion installation during development. Clean and commented code only. Please also FULLY DOCUMENT your work. Thanks again! Thanks for your interest.
