Quandoo
Quandoo is a restaurant reservations marketplace that connects diners with thousands of restaurants and gives merchants table, reservation, and reputation management tooling. Quandoo publishes the Public Partner API, a multi-purpose REST API (host public-api.prod.quandoo.com, authenticated with the X-Quandoo-AuthToken header) that lets partners check merchant availability, search merchants, read merchant reservation and enquiry settings, create and manage reservations and reservation enquiries, manage customers and reviews, handle reservation tags, and validate phone numbers. Reservation and enquiry creation is idempotent via agent-supplied unique identifiers, and returns HTTP 409 when a slot is no longer bookable. Quandoo offers widget, portal, discovery-widget, and direct integration paths plus an interactive API explorer. Note: Quandoo announced in March 2026 that it will wind down operations, with new bookings ending 30 September 2026; this profile documents the still-live Public Partner API as published.
