## Clear call forwarding for a line

**delete** `/api/lines/{sendblue_number}/call-forwarding`

Removes the per-line call forwarding number. After clearing, inbound calls
will fall back to the company default forwarding number (if configured).

This operation is idempotent — calling it on a line with no forwarding set
returns 200 with `forwarding_number: null`.

### Path Parameters

- `sendblue_number: string`

### Returns

- `forwarding_number: string`

  The number calls are forwarded to, or null if not set

- `sendblue_number: string`

  The Sendblue phone number (E.164)

### Example

```http
curl https://api.sendblue.co/api/lines/$SENDBLUE_NUMBER/call-forwarding \
    -X DELETE \
    -H "sb-api-key-id: $SENDBLUE_API_API_KEY" \
    -H "sb-api-secret-key: $SENDBLUE_API_API_SECRET"
```

#### Response

```json
{
  "forwarding_number": "+16692138010",
  "sendblue_number": "+12125550101"
}
```
