Resy is a restaurant reservation and discovery platform owned by American Express. Resy does not maintain a publicly self-serve developer portal; integration is restricted to approved partners (POS, CRM, loyalty, marketing, and discovery) under direct partnership agreements. The primary public surface is the consumer web and mobile app and an embeddable "Book with Resy" booking widget for restaurants. The unofficial internal client API at api.resy.com has been widely reverse-engineered by the community, but it is undocumented, unsupported, and may change without notice.
