As announced in October 2011, with the release of AdWords API v201109, we will be deprecating the following versions and services:
  • AdWords API versions v13, v200909, v201003, v201008, v201101
  • AdWords API version v13 AccountService will only be available on a whitelist basis.
We will be sunsetting these versions and services in 55 days on February 29, 2012. If you have not started migrating to AdWords API v201109, we strongly encourage you to do so, as calls made using previous versions will return errors after February 29th. In particular, we anticipate that migrating from v13 to AdHoc reporting may take some time. Resources to help with this migration are available here. AdHoc documentation is available here and best practices have been outlined on the blog.

We’ve been running the “Discover v201109” blog series to introduce new services, as well as make the migration process easier for you. Posts include:

As with every new version of the AdWords API, we encourage you to review the resources in the AdWords API client libraries. If you have any questions please post them on the AdWords API forum. We will also continue to host Google+ Hangouts with members of the AdWords API Developer Relations Team.

Finally, we may send out periodic service announcements via email on the deprecation timeline and resources to migrate to v201109. Please be sure that your contact information is up to date in your My Client Center account. Review this blog post for more details.
