Microsoft will be retiring the Bing Webmaster Tools SOAP/POX APIs on August 31, 2026. If you use these legacy APIs you should begin to migrate to the JSON/HTTP (REST) API version.
Microsoft's Krishna Madhavan posted a reminder about this both on LinkedIn and X, he said:
ANNOUNCEMENT!! Using the Bing Webmaster Tools SOAP/POX APIs?These legacy APIs will be retired on August 31, 2026. Please review the migration guidance and plan your move to our REST/JSON APIs.
The website about that API has a notice that reads:
Notice: The SOAP and POX/HTTP APIs will be retired on August 31, 2026. After this date, requests to these endpoints will no longer be served. Migrate to the JSON/HTTP (REST) API before August 31, 2026 to avoid service interruption.
Much is not changing including:
- All API methods remain fully available over JSON/HTTP with identical functionality.
- Your API key remains the same — no re-issuance required.
- Quotas, rate limits, and permissions are unchanged.
- JSON/HTTP endpoints continue to be supported and actively developed.
But there are things that are changing.
You can learn more about the JSON/HTTP REST API over here. And you can learn more about what is chaning over here.
