As announced multiple times throughout this year, we are shutting down the Bing Ads API v9/v10 services after today (October 31st). Beginning tomorrow November 1st, they are no longer available to access. In order to have continued programmatic access to the Bing Ads platform, you’ll now need to call the API v11 services. Please refer to the API v11 migration guide for more information.
Please note that with the shutdown of API v9/v10 services, technical support for those services is no longer available. Starting this week, versions 9 and 10 will be removed from the Bing Ads API documentation and SDK libraries.
