Microsoft retires the Partner Center Check Inventory API
Partner Center retires /v1/extensions/product/checkinventory on 25 September 2026 and requires migration to /checkinventorybyresourcetype with a resourceType parameter.
Previous state
Partners checked catalogue inventory through /v1/extensions/product/checkinventory without a resourceType request parameter.
Current state
Integrations must call /v1/extensions/product/checkinventorybyresourcetype and provide resourceType; Microsoft states that the response contract remains unchanged.
Affected users
Who needs to care
Partner Center integrations performing Azure catalogue inventory checks.
Required response
What to do
Add the resourceType request dimension, migrate the endpoint and validate supported resource types before the retirement date.
Evidence boundary
