AdWords API v201702 will be sunset on February 14, 2018. After this date, all v201702 API requests will begin to fail. Given the upcoming sunset of v201705 and v201708 simultaneously in March of 2018, we strongly recommend that you skip v201705 and v201708 and migrate directly to v201710. Please migrate prior to February 14, 2018 to ensure your API access is unaffected.

We've prepared various resources to help you with the migration: As always, if you have any questions about this migration, please contact us via the forum.
