  title: ItsaCheckmate Marketplace for Developers Locations Orders API
  version: '2.2'
  description: 'ItsaCheckmate (Checkmate) is restaurant middleware that connects point-of-sale (POS) systems to delivery marketplaces and online ordering channels. The Marketplace for Developers API is an open REST API that lets technology partners build a single integration to read and write menus, orders, and locations across 50+ POS systems and 100+ ordering platforms.

    Authentication uses an OAuth-style flow: a token endpoint issues short-lived, scoped access tokens (24-hour default expiry) and refresh tokens. After obtaining a token a partner must call the Activate Location endpoint before any menu or order operation will succeed. Menu retrieval requires the `menus` scope. Order submission supports both standard and group orders via a `group_order` flag and requires a verified location.

    Endpoints documented here were confirmed from the official Checkmate developer reference (openapi-itsacheckmate.readme.io) and its llms.txt index. The reference also publishes ready-to-use Postman collections and an Update Notice webhook for real-time menu synchronization.'
