  description: >-
    Self-built enterprise application flow. A tenant creates a self-built app in the
    Fxiaoke admin console (developer mode) and receives appId, appSecret, and a
    permanentCode. These are exchanged for a short-lived access token (called
    corpAccessToken / app access token) that authenticates all subsequent Open API v2
    calls.

  - thirdTraceId   # caller-supplied random trace string

  token_lifetime_seconds: 7200
  caching_guidance: >-
    Token is valid for 2 hours (7200s). Callers must cache it for at least 6600s and
    refresh by re-calling the token endpoint between 6650s and 7200s; the token
    expires at 7200s.

  description: >-
    Modern OAuth 2.1 authorization server discoverable via RFC 8414 metadata at
    https://open.fxiaoke.com/.well-known/oauth-authorization-server. Public clients
    (token_endpoint_auth_methods = none) use PKCE (S256) with authorization_code and
    refresh_token grants, and may self-register via the RFC 7591 dynamic client
    registration endpoint.

notes: >-
  Open API v2 calls carry the token plus tenant context (corpId / currentOpenUserId
  derived from openUserId) in the JSON request body rather than an Authorization
  header. No OpenAPI/Swagger definition is published, so this profile was captured
  from the developer documentation and the live RFC 8414 metadata rather than derived
  from a spec.
