AdWords API v201509 will be sunset on June 21, 2016, after which all v201509 API requests will begin to fail. This version was deprecated on February 2, 2016. If you are still on v201509, we recommend that you skip v201601 and migrate directly to v201603. Please be sure to migrate prior to sunset to ensure your API access is unaffected.
