# POST /api/v1/margin/order stops working

Calls to POST /api/v1/margin/order on KuCoin API stopped working on March 4, 2026.

On March 4, 2026, KuCoin stopped supporting the POST /api/v1/margin/order endpoint. Calls to this endpoint now fail, as it was moved under abandoned endpoints and is no longer available.

## What to use instead

Place margin orders with POST /api/v3/hf/margin/order.
