The Bing Ads V7 API will be removed April 2013. Please migrate your applications from v7 to v8 at your earliest convenience. For V8 API documentation, see Bing Ads API Version 8.
We are currently working on a migration guide to help you migrate to V8. The guide should be available in early November. We will update this post with a link to the guide when it’s available.
We’ve recently provided a V8 API sandbox that you can use to test your migrated application. For information about the V8 API sandbox, see Sandbox.
