  description: Airflow API. All endpoints located under ``/api/v2`` can be used safely, are stable and backward compatible. Endpoints located under ``/ui`` are dedicated to the UI and are subject to breaking change depending on the need of the frontend. Users should not rely on those but use the public ones instead.

  securitySchemes:
    OAuth2PasswordBearer:
      type: oauth2
      description: To authenticate Airflow API requests, clients must include a JWT (JSON Web Token) in the Authorization header of each request. This token is used to verify the identity of the client and ensure that they have the appropriate permissions to access the requested resources. You can use the endpoint ``POST /auth/token`` in order to generate a JWT token. Upon successful authentication, the server will issue a JWT token that contains the necessary information (such as user identity and scope) to authenticate subsequent requests. To learn more about Airflow public API authentication, please read https://airflow.apache.org/docs/apache-airflow/stable/security/api.html.
