Years ago, Payeezy provided me with a super easy PHP script that encryped a total and a couple of values and passed them to the hosted Payeezy payment pages. I was also able to designate IPN URLs in the script and pass those also.
Enter the Clover "upgrade" and I'm kind of lost. At this stage, if I could just get some code that would basically take my simple one item cart total and populate the Clover payment page with it, I would consider it a good start.
Any help I can get is very much appreciated.
