## Overview {#overview}

The reference app is a Python application that makes calls to the Merchant Match Tool API to search the Mastercard Supplier acceptance database.
If you do not have Python already installed, please reference [this link](https://www.python.org/) to download and install Python. If you are not comfortable with running command line prompts would prefer a code editor, you can find one [here](https://jupyter.org/)

A tutorial for the reference application can be located in the ReadMe file in the zip file below.

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.
