title: Hasura Engine HTTP APIs Graphql Version 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.
