notes: >-
  MX Platform API authenticates with HTTP Basic auth over TLS: client_id is the
  username and api_key is the password (Base64 in the Authorization header),
  both issued from the Client Dashboard (dashboard.mx.com). The Consent
  Management API additionally accepts a bearer token. OAuth in MX is an
  institution-connection concern (Data Access / connecting members to their
  banks), not an API-authorization scheme — there is no oauth2 securityScheme in
  the API specs, so no OAuth scopes surface exists.
