Popmenu Developer API
The Popmenu Developer API gives partners access to restaurant data including menus, guests, and orders for building custom integrations with the Popmenu platform. Popmenu also connects with POS and marketing tools such as Square, Toast, Mailchimp, OpenTable, and Yelp. The interface is GraphQL, not REST: a single endpoint at https://api.popmenu.com/graphql was verified live on 2026-08-13 (HTTP 200, application/json) and is mirrored at https://my.popmenu.com/graphql. Introspection and every query return an `unauthorized` error envelope without partner credentials, so the schema cannot be discovered publicly. There is no OpenAPI, Swagger, AsyncAPI or published reference, no documented authentication scheme, and no self-service signup — get.popmenu.com/developer-api is a lead-capture form that lands on a "we'll be reaching out to you soon" page.
