I understand how PayPal standard works and have used IPN previously. I already have that part of code done, have used it very successfully before, and it's ready to go. I understand the PayPal side.
What I am asking is how do I configure eCart to work in the sandbox? What code needs to be changed in eCart. I realize I can dig all over the place to figure it out but there has to be documentation on this right?
My customer has no interest in using PayPal Express or Paypal Pro. Yes, we understand the difference. Does WebAssist have documentation on what code needs to be changed in order to test PayPal Standard in the sandbox and then changed back when going live?
