AdWords API v201601 will be sunset on August 27, 2016, after which all v201601 API requests will begin to fail. This version was deprecated on May 27, 2016. If you are still on v201601, we recommend that you skip v201603 and v201605 and migrate directly to v201607. Please be sure to migrate prior to the sunset to ensure your API access is unaffected.
