    JWT:
      type: http
      scheme: bearer
      description: |
        Synerise uses [JSON Web Token (JWT)](https://jwt.io/) as the authorization method.

        The token is generated by the *auth/login* endpoints.

        You need to include it in the `Authorization` header of your requests, with a `Bearer` prefix.


        By default, the token is valid for **one week** (see [workspace settings](https://hub.synerise.com/docs/settings/tool/iam-for-apps/general/#jwt-lifetime)).  
        You can request a refreshed key for the session by using the *auth/refresh* endpoint **before** the current token expires.


        You can verify your JWT signature by using the [public key](https://api.synerise.com/v4/public.pem).


        See Developer Guides on JWT API authentication for:
        - [profiles](https://hub.synerise.com/developers/api/api-authorization/client-login/);
        - [workspaces](https://hub.synerise.com/developers/api/api-authorization/workspace-login/#api-authentication-with-jwt);
        - [users](https://hub.synerise.com/developers/api/api-authorization/user-login/).
    BasicAuth:
      type: http
      scheme: basic
      description: |
        Basic authentication with login (workspace GUID) and password (workspace API key) encoded with Base64 and sent in the `Authorization` header. **Must be enabled in the settings of the API key**.

        <span style="color:red">This is less secure than JWTs.</span> Limit the API key permissions to only those that you need. Consider API key rotation and other security measures.

        You can still use JWTs from the same API key when basic authentication is enabled.

        For details, see ["Workspace authentication"](https://hub.synerise.com/jwt-or-basic/#basic-api-authentication-with-api-keys).
