Using AIM, how are you supposed to post the data to secure.authorize.net without the use of a form, and return back to your site (I'm working in PHP)? Another question was posted about the exact same matter (with the same title), except they were working in ASP. They concluded that in AIM you don't use a form to post the data to secure.authorize.net but rather a "web post"? The 7th message shows the code to do this in ASP, but I'm not sure what this is or how it's done in php.
-thanks
