Payment Gateway Client


There are several "smaller" merchant payment gateways that all use the same API system. This client is meant to work with all of them. Below is a list of known providers that use this system.

Original documentation:

Known Providers

Note: This is not an indication of endorsement and there is no guarantee of compatibility. With the exception of NMI, these providers have not been tested. Based on current experience, it may be possible to use any of these (and new) providers using the NMI API endpoint though this use case has not been tested.

If you find another gateway that uses this system, please file an issue to get this list updated.
