Merchant Endpoints

Merchant endpoints retrieve transaction details such as: cleansed merchant name, merchant categories, and links to download merchant logos, top-level category icons, and MCC icons (if available). Please see our list of sample transactions for documentation or testing purposes.

Differences between v1 and v2 endpoints.

The V2 endpoint

  • Does not require an MCC in the API request
  • Provides a cleansed transaction description in every API response
  • Enhanced AI similarity merchant matching is applied
  • Post accepts parsing parameters
  • AI matching is deployed


When working with fixed-width strings, parsers offer a method to consistently identify the merchant name, city, state, country and custom attributes within each string to improve match accuracy. Use of parsers is optional and not required.
