**Endpoint:** `POST https://api.higgsfield.ai/wan/v2.6/reference-to-video`

**Endpoint ID:** `wan/v2.6/reference-to-video`

* Supply 1–3 reference videos. This endpoint supports only 5 or 10 seconds, unlike the text and image endpoints that also support 15 seconds.

## Quick start

Replace the example media URLs with publicly accessible URLs for your own files before submitting.

## Response

Submission returns a request handle. Poll `status_url` until `status` is `completed`, or use [webhooks](/docs/how-to/webhooks).

```json Accepted theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "status": "queued",
  "request_id": "REQUEST_ID",
  "status_url": "https://api.higgsfield.ai/requests/REQUEST_ID/status",
  "cancel_url": "https://api.higgsfield.ai/requests/REQUEST_ID/cancel"
}
```

A completed response includes the following output fields:

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "status": "completed",
  "request_id": "REQUEST_ID",
  "video": {
    "url": "https://example.com/output.mp4"
  }
}
```

See [polling](/docs/concepts/polling), [request errors](/docs/concepts/errors) and [authentication](/docs/authentication) for shared request handling.
