In early October, Google announced the launch of a new version of the AdWords API (v201209) which adds several new features including shared budgets, “rotate indefinitely” setting option and Ad group-level demographic targeting. Google has now published a post on the Google Ads Developer blog advising that a new FAQ page has been created to answer questions about the new Shared Budgets feature.

It should be noted that AdWords API v201209 is the most current version. Version v201206 will be sunsetted on February 26, 2013.
