The Microsoft Advertising Community website contains a blog and forum focused on the developer community. The blog contains technical information that is not currently in the MSDN documentation; issues that API customers are facing and clarification and/or a solution to those issues; updates about Sandbox availability; and information about when a version of the service is going to sunset.
The forum provides a way for the developer community to ask and answer questions about developing solutions with Bing Ads APIs, to showcase innovations, and to generate and maintain content through community participation.
You can also contribute content by using the Community Content section located at the bottom of each topic on MSDN. You should not use this section to report defects, suggest new features, or request technical support; instead, you should use the developer community forum mentioned above.
