Google posted a reminder to AdWords API developers that less than 100 days are left before most v13 services will be turned off. “As of April 22, 2010, the following v13 services will no longer be accessible: CampaignService, AdGroupService, CriterionService, AdService, InfoService, KeywordToolService, SiteSuggestionService. However, AccountService, TrafficEstimatorService, and ReportService v13 services will continue to be accessible because they’re not yet available in the v2009 API. In the coming months, we’ll announce the launch dates for these services in the v2009 API and corresponding sunset dates for the v13 services,” stated Jason Shafton.
