Is there free credit card api or payment gateway?

Actualy question says all, I need this only for testing. So, demo of some kind or 4开发者_开发百科-5 free transactions a day will do a trick.

Not looking for anything fancy.

Is there anything free?

Use a paypal developer account. They have a sandbox that is identical to the real thing except it doesn't process transactions.

If you use the back end webservice functions (not the forms based api) it should do what you want.

I dont' think it will do AVS for you though.

If you sign up for an Authorize.Net developer account you can run an unlimited amount of test transactions for free.

Revolution payments https://www.revolution-payments.com can provide a free solution for testing. We use them and their tokenization and vaulting feature

The fact they share in credit card processing residuals is also a plus
