note: >-
  Cleo publishes no OpenAPI, so this profile is not derived from a spec. It is read
  verbatim from the one machine-readable authorization document Cleo serves publicly:
  an RFC 8414 OAuth 2.0 Authorization Server Metadata document at
  https://www.meetcleo.com/.well-known/oauth-authorization-server (HTTP 200,
  application/json, issuer https://www.meetcleo.com).
scope_of_this_record: >-
  IMPORTANT — this is NOT a third-party developer authorization surface. A GET of the
  advertised authorization_endpoint (https://www.meetcleo.com/oauth/authorize) returns
  302 to https://www.meetcleo.com/admin_log_in, an internal administrative sign-in.
  Cleo runs no public developer program and issues no third-party API credentials, so
  the metadata below documents an internal/administrative OAuth deployment that happens
  to be discoverable at the standard well-known path. It is recorded because it is real
  and published, not because it is callable by an outside integrator.

    grant_types_supported: [authorization_code, refresh_token]
observations:
  - >-
    token_endpoint_auth_methods_supported is ["none"], which with PKCE S256 is the
    public-client profile — the deployment expects clients that cannot hold a secret.
  - >-
    No registration_endpoint is advertised, so there is no RFC 7591 dynamic client
    registration; clients must be provisioned out of band.
  - >-
    No /.well-known/openid-configuration is served (404 on every host probed), so this
    is plain OAuth 2.0, not OpenID Connect.
  - >-
    No jwks_uri, introspection_endpoint or revocation_endpoint is advertised.
