Webhooks

Async media tasks can include a callback URL when enabled for the API key or request. Callbacks are retried by the platform when delivery fails. The callback body is the same shape as the task detail. The result differs by task type: image results carry result.data[0].url, while video/audio results carry result.video_url / result.audio_url (and result.urls[]).

{
  "task_id": "task_123",
  "status": "completed",
  "model": "seedance-2.0",
  "type": "video",
  "result": {
    "status": "completed",
    "video_url": "https://.../video.mp4",
    "urls": ["https://.../video.mp4"]
  }
}

Recommendation

Always verify task status through /v1/tasks/{task_id} before treating a webhook as final in high-value workflows.
