Response Example
{
"name": "models/veo-3.1-generate-preview/operations/abc"
}
Query Task
The operation_id can be obtained from the response of the predictLongRunning endpoint.
After a successful query, the API returns a URL (response.generateVideoResponse.generatedSamples.video.uri) for downloading the video. This URL is required when making the request.
