  }'

Infill Mode

When is_infill: true is set, Suno will automatically generate transition passages between song segments:

{
  "clip_id": "clip_abc123",
  "is_infill": true
}

After submitting a concatenation task, use the Task Query endpoint to get results. The concatenated song will generate a new clip ID.
