Verified production IndexNow receipt with a new key: Microsoft's external proof returned HTTP 200, single-URL GET and POST both returned HTTP 200, and eight batches covering 386 canonical URLs each returned HTTP 200 with zero retries. A second run found the inventory unchanged and sent no request.
What changed
01
Verified the new root key externally through Microsoft's production validation path with HTTP 200 without exposing the key.
02
Confirmed both the single-URL GET and single-URL POST submission shapes returned HTTP 200.
03
Set the production batch size to 50 and received HTTP 200 for all eight batches covering 386 canonical URLs, with zero retries.
04
Confirmed a second run detected an unchanged inventory and sent no request, preserving the persisted idempotent state.
05
The final production verifier reported 69 passes, zero failures, and one AdSense account warning. IndexNow HTTP 200 records receipt only, not crawling or indexing, and the separately submitted Bing sitemap remains processing.
