# POST /parcels/v1/shipment/activatereturn stops working

Calls to POST /parcels/v1/shipment/activatereturn on PostNL API stopped working on August 1, 2026.

On August 1, 2026, PostNL API removed POST /parcels/v1/shipment/activatereturn. Requests sent to this endpoint are no longer accepted and fail with an error response.

## What to use instead

Stop creating Shipment and Return labels using Characteristic 152 or Option 026 and remove the handover blockade. Because the service is withdrawn without a direct replacement, redesign returns to manifest each return as a new return shipment with a new barcode using Returns API v4 or a return label.

The Shipment and Return label service is withdrawn with no direct replacement; returns must be redesigned as separate return shipments.
