                  There is no specific error message to indicate that a request has failed because
                  an access token has expired; instead, if a client has reason to believe its
                  access token is valid, and it receives an auth error, they should attempt to
                  refresh for a new token on failure, and retry the request with the new token.

                type: string

                  Optional. A ``refresh_token`` may be exchanged for a new ``access_token`` using the |/tokenrefresh|_ API endpoint.

      summary: Exchanges a refresh token for an access token.
      description: |-
        Exchanges a refresh token for a new access token.
        This is intended to be used if the access token has expired.

        The server MUST invalidate the supplied ``refresh_token`` if the
        request is successful. It MUST also invalidate the ``access_token``
        which was issued at the same time as the ``refresh_token``, if it
        has not already expired.

            A new refresh token will have been returned unless some policy does
            not allow the user to continue to renew their session.
