# POST /post-order/v2/return/{}/mark_refund_received stops working

Calls to POST /post-order/v2/return/{id}/mark_refund_received on eBay API stopped working on January 20, 2026.

On January 20, 2026, the POST /post-order/v2/return/{id}/mark_refund_received endpoint was decommissioned and removed from the documentation. Requests to this endpoint now fail. The change affects all integrations calling this Post-Order API operation to mark return refunds as received.

## What to use instead

eBay names no replacement for this Post-Order call. Because the call was removed without an equivalent API replacement, deciding what the code should do with this step requires a product decision to handle it directly on eBay or drop the step entirely.

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