# Terminate a storage volume

`POST /v2/alpha/on-demand/storage-volumes/terminate`

> **Deprecated.**

**Deprecated.** This path is the pre-`/v2/` URL for `/v2/on-demand/storage-volumes/terminate` and is kept only so existing integrations keep working. It behaves identically, responds with a `Sunset` header, and stops being served on 2027-03-01. Move to `/v2/on-demand/storage-volumes/terminate`.
