  title: Eat App Platform Concierge - Availability Concierge - Reservations API
  description: 'Eat App is a restaurant reservation and table management platform. This document models its two documented, partner/key-gated REST surfaces plus a small honestly-modeled table-management surface:

    1. Partner API (base /partners/v2) - for booking channels to read availability and post reservations.

    2. Concierge API (base /concierge/v2) - for restaurants, vendors, and groups to sync reservations, guests, availability, and reference data (resources, groups, restaurants). Requests are scoped with X-Group-ID and X-Restaurant-ID headers and can be created idempotently via an idempotency_token.

    3. Tables and Floor Plans (base /concierge/v2) - MODELED. No public tables or floorplan endpoints are documented; these operations are honestly modeled on Eat App''s documented resource conventions and should be confirmed with a partner API key before use.

    All responses follow a JSON:API-style structure (data objects carrying id, type, and attributes). Every request is authenticated with a Bearer token (the API key Eat App issues to a partner or Concierge user). The sandbox host is https://api.eat-sandbox.co and production is https://api.eatapp.co. Endpoints are rate limited to roughly 60 requests per minute.'
