GatewayAPI.com documentationΒΆ

Our documentation is broken into a few parts based on protocol. All new customers are encouraged to use the new REST API. However we also provide a few legacy APIs based on SOAP and HTTP POST/GET, which are still maintained although deprecated.

If you are reading this online at https://gatewayapi.com/docs/ and require any assistence, please use the live chat feature at the bottom right of your screen.

You can also consult the HTTP Routing Table

In addition to our dashboard, which you can find on https://gatewayapi.com/app/, we also offer programmatic access to a few of the functions offered in the dashboard. You will find the documenation for these at https://gatewayapi.com/docs/website/

Writing and improving this documentation is an ongoing effort. Pull requests etc are most welcome. https://github.com/onlinecity/gatewayapi-docs
