notes: >-
  Celonis Platform APIs authenticate via the Authorization header. OAuth 2.0 is the
  recommended method (User API Key and Application API Key are deprecating). OAuth
  access tokens are short-lived (~899s / 15 min) and support refresh; client secrets
  can be rotated. Client-credentials (machine-to-machine) and authorization-code
  (user delegation) grants are supported, with client_secret_basic and
  client_secret_post client authentication. Base host is
  https://{team_domain}.{realm}.celonis.cloud; token endpoint is
  https://{team_domain}.{realm}.celonis.cloud/oauth2/token.
