Are there testing credit card numbers to use with GetPaid?
GetPaid actually validates credit card numbers on the checkout, so even if you are testing the system and using the test payment processor, you must use real credit card numbers. This document tells you where you can get real fake credit card numbers, so your testing doesn't become an expensive habit!
well, yes...but unfortunately Authorize.net makes them hard to find and impossible to link to (they used to be here). Now you have to go to the Knowledge Base and search for "credit card numbers for testing". It should be the first link that comes up (Testing Card Numbers).
