Bing Webmaster API to deprecate POX and SOAP APIs

One era is coming to an end with Bing, when the Webmaster Tools (WT) related APIs are depecating both the so-called POX API and the, well, older SOAP API. It's a long time since Microsoft has actually talked SOAP anywhere, but Bing tools seem to have been an exception.

These two APIs stop working at the end of August, 2026. This means that from that point onwards, the HTTP JSON (REST) API is the only one that works.

How do you tell which one you are using? All the three APIs use HTTP, so you look into the URLs of your Bing API calls. If you see:

• https://ssl.bing.com/webmaster/api.svc/pox/... you need to fix it,
• https://ssl.bing.com/webmaster/api.svc/soap/... you need to fix it as well,
• https://ssl.bing.com/webmaster/api.svc/json/... you are good!

More details are available the Bing WT site's article "SOAP and POX API Endpoints Retirement".
