I'm having trouble with this...maybe because it's difficult to test, it doesn't popup or display any result. In my url, I setup a php script to just print all the $_POST variables to an email...which works, I tried it externally, but after a transaction, the url isn't even opened.
Is there something I need to do other than the ?postto=URL...or something in the php script, does it not read variables through $POST or $GET?
