Hi, It looks like the server integration method is exactly the product I
need. However my server is running php4... Is there an SDK that I can
download which will work for php4. Thanks, Mack
Sorry, I just did a search and found
this:http://community.developer.authorize.net/t5/Integration-and-Testing/x-fp-hash-issues/m-p/8548
Which pretty much answers my question.
