*ESTIMATED TIME TO COMPLETE THIS TUTORIAL: 10 MINUTES*

This guide walks through the steps required to create a new Merchant Match Tool (MMT) API project and how to gain access to the Sandbox environment.

Please note that the data returned in the Sandbox environment is placeholder data. While the data types reflect what will be returned in a production request, the underlying matching algorithm is not accessed. Thus, responses in the sandbox environment may change between requests.
