Verdicts

OpenTable APIs

The public documentation covers diner-side and venue-side booking in detail, with slot locks, policy endpoints, error tables and an X-Request-Id header for safe retries. Access needs partner approval and a contract, rate limits and prices are not published, and the status page and main website could not be read.

TheFork B2B API

A venue-side API with a generated OpenAPI 3.1 schema, an llms.txt written for agents and nine OAuth scopes down to read-only availability. It acts for restaurants and their vendors, not diners, needs partner approval, cannot take card guarantees, and has no public status page, changelog or published prices.

Before you call either

OpenTable APIs

  1. Lock the slot before calling Make Reservation, since the lock and its reservation_token expire within 5 minutes
  2. Send a unique X-Request-Id on every POST, PUT and PATCH so a retried booking is not duplicated
  3. Fetch booking and cancellation policies before booking and show any deposit, hold or service fee to the diner
  4. Use the Consumer API for diner bookings and the In-House Booking API only for a restaurant's own voice or phone channel
  5. Ask the OpenTable representative for the rate limit of each endpoint before going live

TheFork B2B API

  1. Read hasPaymentGuaranteeRequirement in the timeslots response before booking, since the API cannot take a card
  2. Check the status field after creating a reservation and treat REQUESTED as unconfirmed
  3. Send the timeslot datetime unchanged as mealDate, because times are the restaurant's local time
  4. Check for an existing reservation before retrying a failed POST, as no idempotency key exists and 409 signals DOUBLE_BOOKING
  5. Cache the access token for its 8,600 seconds and do not request a new one while it is valid
