# Suspend a line

`POST /v1/numbers/{numberId}/suspension`

## Request

- Base URL: `https://api.telgea.com`
- URL: `https://api.telgea.com/v1/numbers/{numberId}/suspension`
- Auth: API key in header `x-api-key`

Stops all traffic on one line, domestic and international — for a phone that has been lost or stolen. To stop only mobile data and leave the line usable, use the data-restriction endpoint.

The call returns once the line is down at the network, so a `204` means the service is genuinely stopped.

Suspending a line that is already suspended returns `409` and changes nothing.

Not every market offers suspension. Where it does not, this returns `400` and the line stays live — the Markets page in the documentation lists which is which.

## Path parameters

- `numberId` string, uuid, required: UUID of the line.

## Headers

- `idempotency-key` string: A value unique to this request, of 1 to 255 printable ASCII characters — a UUID is the usual choice. Retry with the same key within 24 hours and you get the original response back, even if it was a failure, and nothing is done twice. Send a new key whenever you change the request. Keys are private to your API key and organisation.

## Response `204`

Line suspended. No content returned.

## Other responses

- `400`: Request failed schema validation, or was refused by a business rule
- `401`: Missing or invalid API key in the X-API-Key header
- `403`: Insufficient permissions for this action
- `404`: No line in your organization has this id.
- `409`: Already in the state you asked for, so nothing was changed.
- `429`: The API key has used its request quota for the current window. `Retry-After` says how many seconds until it resets.
- `500`: Internal server error. Contact support if this persists.
