I need an integration script for an online check drafting system. I will post data to the script. The script should processing the information via the included API method. Upon a successful transaction, the script should redirect the user to the thankyou page, if there is an error or a declined transaction, the script should display an error message as appropriate.
The script should be php 3.4... compatible. Let me know if you need to see my php settings or any other information.
