What can the API do for you?

The MX Platform API provides a wide range of features that allow banks, fintechs, and other financial institutions to give end users an exceptional experience. These include:

  • Account and transaction data aggregation from tens of thousands of institutions.
  • For some institutions, up to 24 months of transaction data can be gathered in a single request.
  • Held data can be managed entirely on your own while still maintaining access to the other features of the API.
  • Industry-leading data enhancement out of the box, including automatic transaction categorization and classification, custom categorization by end users, and description cleansing.
  • Enhancement for non-aggregated data provided directly from your own systems.
  • Account verification — often eliminating the need for microdeposits — as well as owner identification.
  • Personalization including transaction rules, custom tags, and custom categories.
  • MX’s award-wining personal financial management widgets, including Connect, which automates aggregation and account verification.
  • Merchant data for thousands of businesses and vendors.
