Broadcasts

Broadcast cancelled

broadcast.cancelled

Fires when a broadcast run is cancelled, either before sending begins or while it is in progress. Messages that were already sent are not recalled.

HTTP request

AISAR sends a signed POST request to your webhook_url:

http

POST {webhook_url}
Content-Type: application/json
X-AISAR-Signature: sha256=...

{
  "event": "broadcast.cancelled",
  "event_id": "evt_01JXXXXXXXXXXXXXXXXXXXXX",
  "timestamp": "2026-03-26T10:10:00.000000Z",
  "company_id": 1,
  "data": {
    "broadcast": {
      "id": 8,
      "name": "March Promo",
      "status": "cancelled",
      "channels": [2],
      "created_at": "2026-03-26T10:00:00.000000Z"
    }
  }
}

The X-AISAR-Signature header carries an HMAC-SHA256 signature of the request body — use it to verify the request came from AISAR.
