# Construct headers
            header_parameters = {}
            header_parameters['Accept'] = 'application/json'
            if self.config.generate_client_request_id:
                header_parameters['x-ms-client-request-id'] = str(uuid.uuid1())
            if custom_headers:
                header_parameters.update(custom_headers)

                header_parameters['accept-language'] = self._serialize.header("self.config.accept_language", self.config.accept_language, 'str')

            # Construct and send request
            request = self._client.get(url, query_parameters, header_parameters)
            response = self._client.send(request, stream=False, **operation_config)

            if response.status_code not in [200]:
                raise models.ErrorException(self._deserialize, response)
