## Webhook (Optional)

Add the `X-Webhook-URL` header to your submit request to receive a `POST` callback when the job completes — no polling required.

### Webhook Headers

Header

Required

Default

Description

`X-Webhook-URL`

Yes (to enable)

—

HTTPS endpoint on your server that will receive the `POST` callback. Must respond `2xx` within a few seconds (process async if needed).

`X-Webhook-Mode`

No

`terminal`

`terminal` — fires once at the final status (`COMPLETED`/`FAILED`/`ERROR`). `sync` — fires on every poll cycle plus the terminal event, and caps the queue’s polling delay at **15s** for tighter progress updates.

### Example: enable webhook

```
X-Webhook-URL: https://your-server.com/webhook/callback
X-Webhook-Mode: terminal
```

### Callback Payload

Your endpoint receives a `POST application/json` with the same shape as the `GET /v2/requests/status/{request_id}` response. Example terminal callback (mode `terminal`):

```
{
  "request_id": "luma-dream-machine-ray-2-flash-image-to-video_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "status": "COMPLETED",
  "model_id": "luma-dream-machine-ray-2-flash-image-to-video",
  "error": null,
  "output": {
    "media_url": [
      "https://pub-582b7213209642b9b995c96c95a30381.r2.dev/v1/luma-dream-machine-ray-2-flash-image-to-video_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/output.mp4"
    ],
    "media_type": "video/mp4"
  },
  "created_at": "2026-05-22T13:17:32.110Z",
  "updated_at": "2026-05-22 13:19:23",
  "completed_at": "2026-05-22 13:19:23"
}
```

### Failure callback shape

```
{
  "request_id": "luma-dream-machine-ray-2-flash-image-to-video_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "status": "ERROR",
  "model_id": "luma-dream-machine-ray-2-flash-image-to-video",
  "error": "Description of the error",
  "output": null,
  "created_at": "...",
  "updated_at": "...",
  "completed_at": "..."
}
```

### Delivery semantics

-   **terminal mode (default)** — exactly one `POST` when the request reaches a terminal status. No callback during `PROCESSING`.
-   **sync mode** — `POST` on every status poll (with delay capped at ~15s) plus a final `POST` at terminal status. Use when you want progress updates.
-   **Idempotency** — use `request_id` as your idempotency key. Network retries can deliver the same callback more than once; your handler must tolerate duplicates.
-   **Response** — respond `200 OK` within a few seconds. The queue does not block on slow handlers, but persistent failures may stop further deliveries.
-   **HTTPS required** — plain `http://` URLs are rejected.

## Typical Workflow

1.  **Send a generate request** to the API endpoint
2.  **Save the `request_id`** from the response
3.  **Poll** every 5-10 seconds: `GET /v2/requests/status/{request_id}`
4.  **When `status` is `"COMPLETED"`**, download from `output.media_url`

**Tip:** Use `X-Webhook-URL` header to get a callback instead of polling.
