Authelia API
The full first-party Authelia HTTP API — the portal, authorization, authentication, second factor, user information, session elevation, password reset/change and OpenID Connect 1.0 surfaces. Described by Authelia's own OpenAPI 3.2.0 contract (42 paths, 78 operations, 100 schemas), published in the Authelia repository at api/openapi.yml and served by each deployment. Authelia is self-hosted, so the base URL is the operator's own deployment host; auth.example.com is the default Authelia's own contract template uses.
Authelia API is one of 4 APIs that Authelia publishes on the APIs.io network, described by a machine-readable OpenAPI specification.
Tagged areas include Authentication, Authorization, MFA, OpenID Connect, and SSO. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and a GitHub repository.
This API exposes 78 operations across 42 paths, organized into 12 resource areas, and defines 100 schemas. It is described by OpenAPI 3.2.0, at version 1.0.0.
Requests are made against a single base URL, https://{authelia_host}.
