90-DAY REMINDER: Migrate to API v12
With the release of Bing Ads API v12 early in April, we announced the sunset of API version v11 will happen on October 31, 2018. If you are currently using API v11, which is now deprecated, this is a courtesy reminder for you to migrate to API v12 by the sunset date.
If you need details on migrating to v12, refer to this guide. Please bear in mind that we cannot guarantee availability of the older services after the sunset date, so to have continued access to our API, please migrate before October 31st.
