We’d like to remind you that v201306 of the AdWords API and Ad Exchange Buyer SOAP API are scheduled to be sunset on March 31st, 2014. Start your migration to v201309 now to avoid having your API calls fail on the sunset date. If you are still using ClientLogin, we strongly recommend that you also migrate to OAuth2.

The following will help you to migrate to v201309:

• Announcement blog post for v201309 — includes highlights of v201309
• Release notes — lists every API change and version diffs
• Migration guide — includes a listing of breaking changes between v201306 and v201309
• Client libraries and samples page — updated official client libraries
ClientLogin to OAuth2 migration — detailed guide on OAuth2 implementation

For migration help, contact us on the AdWords API forum or Ad Exchange Buyer API forum. Our Google+ page is also a great resource for keeping up-to-date with the latest announcements and communicating with us.

If you often need to retrieve a list of recently changed objects, the CustomerSyncService can help you save many API requests. We’ve made several improvements to this service in AdWords API v201306. These include integration with feed services and exposing ad group bid modifier change information.

Feed Services, first available in v201302, allow you to manage reusable ad extensions in a modular way. The latest changes to the CustomerSyncService enable you to retrieve changes to Feeds using a CustomerSyncSelector. Specifically, you can now retrieve feed update details based on a list of FeedIds you specify.

The other main improvement to the CustomerSyncService is the inclusion of CampaignCriteria which contains ad group-level bid modifiers.
