The POS Gateway takes card-present payments for a point of sale: it drives the merchant’s CardPointe terminal, authorizes through CardConnect, and answers the POS with the result. There’s no payment server to run in the store.

​
Two ways to connect

Call the API

For a POS that can make HTTPS requests: send each action to the gateway and read the JSON or XML answer.

Use the Mojo Payments CLI

For an on-premises POS that runs a program and reads a file: the mojo command does the HTTPS call for it.
Either way, the POS needs a POS Gateway key for each register (Keys).

​
Your POS

Some point-of-sale systems have their own setup steps. See the POS guides.

​
Before you start

The merchant needs POS Gateway turned on at the location, the location’s MIDs ready, and a key made for each register. See POS Gateway for merchants.
