Fed up with searching for documentation of test payment cards for specific payment gateways the other day I decided to start compiling a cheatsheet of them. It can be frustrating trying to figure out what card numbers can be used for testing especially considering the many poorly documented payment gateways out there. So I created the Test Payment Cards cheatsheet repository.
I decided to create the cheatsheet as a GitHub repository rather than a page on this site so that others can fork it and contribute; this way the list can be kept up to date and test cards for other missing payment gateways can be added.
So far the repository contains card numbers for popular payment gateways like PayPal, SagePay and Stripe as well as some more unknown ones like Ogone and RedSys.
The cheatsheet is licensed under a Creative Commons Attribution-ShareAlike license.
If this sounds like something that could be useful to you go star and/or fork it from the Test Payment Cards repository now.
