## Overview {#overview}

Mastercard Merchant Match Tool (MMT) is a service that matches user's Suppliers against the Mastercard Supplier acceptance database.
For identified Suppliers, MMT provides access to key Supplier-level data for commercial card program planning and analysis including: Merchant Category Code (MCC), level of clearing data provided and transaction recency data.

Mastercard Merchant Match Tool enables Issuers, Payment Service Providers or Corporates to launch new commercial card programs or optimize existing ones with measurable approaches to:

* Manage cardable expenses and increase process efficiency
* Quantify and pursue spend opportunity with higher confidence
* Improve cash flow and working capital management
* Identify additional rebate opportunities and more

<br />

The Mastercard Merchant Tool Application Programming Interface (API) allows users to access the Merchant Matching Engine for real-time querying and match results.

The benefits of the MMT APIs are:

* Enhanced MMT user/client experience through an API interface
* Streamlined process for a quicker turnaround of client queries
* Allows for handling multiple Suppliers within the same request
* Aligns with market competitor and technology paradigms

## How It Works {#how-it-works}

![how_it_works](https://static.developer.mastercard.com/content/merchant-match-tool/uploads/how-it-works.png)

The MMT API allows users to access the Merchant Matching Engine for real-time querying by making an API call with a pre-defined request format. The API call is routed to the Merchant Matching Engine and the match results are shared with the requestor in a pre-defined response format. The API response will have the status code and best matched Supplier.

The solution includes two APIs: one to handle single query search requests and another for multiple query search requests. Each client will have its own API-key for authentication which will be provided as the part of client onboarding process.
