Reminder: Check Inventory API retiring September 25, 2026

Reminder: A new Check Inventory by Resource Type API is now available. The previous Check Inventory API will retire on September 25, 2026.

Impacted audience

All partners using Partner Center APIs for inventory checks.

As previously announced, a new Check Inventory by Resource Type API is now available, enabling partners to check inventory for catalog items filtered by a specific resource type. Microsoft introduced this new API to handle the growing complexity of Azure services, where availability also depends on resource type. By requiring a resourceType parameter, it enables more scalable and performant inventory checks to address data growth challenges without changing the API response contract.

This API replaces the existing Check Inventory API, which retires on September 25, 2026.

Next steps

• Review the Check Inventory by Resource Type API documentation for supported resource types and usage examples.
• Update your integrations to use the new API before September 25, 2026.
