Checkout API Overview

The MX Merchant Checkout API is organized around REST and is designed to have resource-oriented, predictable and easy-to-use HTTP response codes to indicate API interaction. A sandbox testing environment is provided so that, prior to working with live data, testing can be performed to understand the requirements of making successful calls to each API resource. Any payment data submitted in the testing environment will not be transmitted to the credit card networks and will never actually initiate a payment or attempt to move money.

We offer 2 environments, each having its own merchant interface – Production and Sandbox. Each environment you wish to interact with will require its own consumer key and secret.

To create a test account, please reach out to your Agent or Relationship Manager and our API Help team.
