AdWords API v201605 will be sunset on March 28, 2017, after which all v201605 API requests will begin to fail. This version was
deprecated on July 28, 2016. If you are still on v201605, we recommend that you skip v201607 and v201609 and migrate directly to v201702. Please be sure to migrate prior to the sunset to ensure your API access is unaffected.
We've prepared the following resources to help you with the migration:
As always, if you have any questions about this migration, please contact us via the
forum.
