# Release a rented phone number

`POST /product/release-number`

Releases a phone number previously rented via `POST /product/rent-number`. The number goes back into provider inventory and recurring charges stop.

Returns `400` if the number is still assigned to an agent — detach it from the agent first (`PATCH /agent/{agentId}` with `productId: null`).

## Request body

- object
  - `productId` string, required — 24-char hex MongoDB ObjectId of the phone-number product to release (the `_id` value returned by `GET /product/phone-numbers`).

## Response `200`

Number released

- object
  - `status` boolean
  - `data` object
    - `success` boolean

## Other responses

- `400` — Number is still assigned to an agent (detach it first), or invalid product ID format.
- `401` — Unauthorized access
- `500` — Internal server error
