notes: >-
  No OpenAPI/Swagger spec is retrievable (the Stoplight-hosted docs at
  api-docs.fidor.de and api-docs.sandbox.fidor.com are offline and fidor.com is a
  parked domain), so this profile is searched from the official Ruby client's
  documentation rather than derived from a spec. The Fidor REST API used OAuth2
  with the authorization-code flow; bearer access tokens were then presented to
  the API.

    description: >-
      OAuth2 authorization-code flow. The official Ruby client exposes
      authorize_start / authorize_complete helpers to obtain an access token
      that is then used as a bearer token against the classic transfer, account
      and transaction APIs.
