345992 Script for payment processor

I need a callback script for zombaio a payment processor. I have their default one, but i do not require their user/password generator. Just need the script to have callbacks to the site. ZOMBAIO POST BACK API DESCRIPTION If you have any reason you cannot or will not use Zombaio's ZSCRIPT file, you can program your own. It is important that your own file responds with the same data as a Zombaio ZSCRIPT file. Below you will find a display of the different function calls that Zombaio's platform has against the ZSCRIPT file and how you should respond to the different calls. By default, the file that is called is [login to view URL] but can be changed in ZOA (Zombaio Online Administrator) to an optional file in an optional programming language. Need help.
