  title: Grubhub Merchant Data API
  description: >-
    The Grubhub Merchant Data API provides endpoints for managing merchant
    information, including store details, tax rates, fulfillment settings,
    and configuration groups. Partners can retrieve all Grubhub locations
    associated with a merchant's account, update merchant profiles, and
    manage operational settings such as online/offline status. This API is
    essential for maintaining accurate restaurant data across the Grubhub
    platform.
