90-DAY REMINDER: Migrate to API v11
With the release of Bing Ads API v11 in early May, we announced the sunset of API versions v9 and v10 on October 31st. If you are currently using either of the deprecated API versions, this is a courtesy reminder for you to migrate to API v11 by the sunset date.
If you need details on migrating to v11, refer to this guide on MSDN. 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.
If you have any questions in this regard, feel free to reach out to us on the Bing Ads developer forums or contact us at bingads-feedback@microsoft.com.
