Most Version 9 Services will Sunset on June 30

As previously mentioned when we released Bing Ads API Version 10, the Ad Intelligence, Bulk, Campaign Management, and Optimizer Version 9 services will sunset on June 30, 2016. You must upgrade to version 10 by that date. For details on what has changed in version 10, see Migrating from Bing Ads API Version 9 to Version 10. If you have any questions, please feel free to contact support or post something in the Bing Ads API developer forum.

Please note that the Customer Billing, Customer Management, and Reporting Version 9 services will not be sunset at this time. Later this summer we will announce details about the upgrade path for those services.
