  description: >-
    OAuth 2.0 Client Credentials flow. During onboarding the customer receives a
    clientId and clientSecret, which are exchanged at the Auth0 token endpoint
    (separate production and sandbox endpoints) with grant_type=client_credentials
    for an access_token. The bearer access token must be included in the
    Authorization header on every API request. Tokens expire (e.g. expires_in
    86400 = 24h). The authorization flow must be handled exclusively by a secure
    backend; web frontends and mobile apps must not call the API directly or
    expose the clientSecret.

scopes_documented: false
scopes_note: >-
  The Pro API does not document OAuth scopes/permissions; access is scoped by the
  onboarded client credentials rather than per-request scope grants.
callback_authentication: >-
  Inbound callbacks (webhooks) can be verified via Ed25519 signature headers, and
  Pliant can optionally deliver callbacks with OAuth 2.0 authentication.
