How to Build Booking Into Your Product Across OpenTable, Yelp, SevenRooms, and resOS

Booking integrations in SaaS products allow users to search locations, view available time slots, and make reservations directly within the product, leveraging the Unified Commerce API to streamline this process across various platforms like OpenTable, Yelp, SevenRooms, and resOS. These integrations are complex due to varying structures of availability, time filters, and reservation payloads, often requiring separate logic for each platform. The booking flow involves four core objects: location, availability, reservation, and review, with availability being read-only and reservations serving as the write path. While the object model remains consistent across integrations, the behavior and capabilities differ, such as reservation support and webhook availability. The Unified Commerce API provides a consistent API surface and data model, allowing developers to build a single booking flow that adapts to the unique behaviors of each integration, simplifying development while accommodating platform-specific limitations.
