  notes: >-
    PlainID exposes two authentication surfaces. Runtime (PDP) Authorization
    APIs authenticate with a clientId/clientSecret pair (request body or the
    X-Client-Id / X-Client-Secret headers) or a JWT bearer token verified
    against the configured issuer JWKS. Management / Administration APIs use an
    OAuth 2.0 Client Credentials flow (which replaces the older IDP token-exchange
    flow) against the tenant Keycloak realm, returning a Bearer access token.

      Client credentials are created at the Tenant or Environment level and
      replace the legacy IDP token-exchange flow. The returned token is sent as
      an Authorization Bearer header on Management and Administration API calls.
