Stop a subscription and free its slot. Use this when you no longer want events, or before creating a replacement of the same type. Deliveries stop immediately, including any queued retries.

Prerequisites: a Partner bearer token and the subscription's id (from List your webhooks).

Authentication: Partner token. Only partner users can call it; other tokens get 403. Only your own partner's subscriptions: any other id gets 404.

Rate limit: none.
