  title: Hasura Engine HTTP APIs Graphql Query API
  description: 'Hasura GraphQL Engine exposes a small set of HTTP APIs in addition to its

    GraphQL endpoint. This specification documents the most commonly used

    endpoints: GraphQL queries/mutations/subscriptions, Relay GraphQL, the

    Metadata API, the Schema API, the PG Dump API, the Explain API, the

    Health Check API, the Source Health Check API, the Config API, and the

    Version API.


    Authentication: When the engine is started with HASURA_GRAPHQL_ADMIN_SECRET,

    requests must include the `x-hasura-admin-secret` header (or a valid JWT).

    Roles and session variables are passed via `x-hasura-role` and any

    `x-hasura-*` session headers.
