def _get_body(self, response):
        if response.status_code != 200:
            raise googlemaps.exceptions.HTTPError(response.status_code)

        body = response.json()

        api_status = body["status"]
        if api_status == "OK" or api_status == "ZERO_RESULTS":
            return body

        if api_status == "OVER_QUERY_LIMIT":
            raise googlemaps.exceptions._OverQueryLimit(
                api_status, body.get("error_message"))

        raise googlemaps.exceptions.ApiError(api_status,
                                             body.get("error_message"))
