As part of the upgrade to enhanced campaigns, we have shared updates about the AdWords API v201209 sunset. Today's note is to provide a 2 weeks reminder that v201209 sunsets on July 22nd and API requests will start failing after that date. With the sunset deadline only a few weeks away, if you haven’t already migrated to v201302 or v201306, it is recommended that you do so as soon as possible. See below for further information on migrating.
