# TextProtect Webhook

To receive notification on every unauthorized attempt for changing your number messaging provider please provide an URL that exposes HTTP POST endpoint and accepts the body model like in the example below.

```json
{
 "number": "1200300400",
 "sms_account": "TSG100000",
 "requester_nnid": "123456",
 "requester": "carrier",
 "timestamp": "2023-03-30T08:14:19.688501",
 "description": "Request rejected by TextProtect"
}
```

Please respond with 200 OK on success, otherwise, our webhook will retry for the next 72 hours with exponential backoff. If we are unable to deliver the webhook after 72 hours the retry will stop.
