  title: Slab GraphQL API
  description: >-
    HTTP transport for the Slab GraphQL API. Slab exposes a single GraphQL
    endpoint at https://api.slab.com/v1/graphql accessed via HTTP POST with a
    JSON body containing a `query` and optional `variables`. Authentication uses
    an `Authorization` token generated in Team Settings -> Developer Tools. The
    API is available to Business and Enterprise customers and returns only
    content accessible to the Slab Bot user.
