# POST /post-order/v2/cancellation/{}/confirm stops working

Calls to POST /post-order/v2/cancellation/{id}/confirm on eBay API stopped working on March 2, 2026.

On March 2, 2026, eBay decommissioned the POST /post-order/v2/cancellation/{id}/confirm endpoint and removed it from documentation. Calls to this endpoint fail after this date. This change affects integrations using the Confirm Cancellation Refund call.

## What to use instead

eBay names no replacement for this Post-Order call. You must handle the step on eBay or drop it, which requires a product decision regarding what your code did with the call.

eBay removed the call without a replacement: what the code did with it is a product decision.
