# Studio Add Section Commit

> Phase 2 — commit a selected add-section candidate

Commit the candidate chosen from [Add Section](/api-reference/suno/studioAddSection). Poll [Get Task Status](/api-reference/suno/task) until `success`.

<Info>
  **Free** (0 credits). `taskId` is the **phase-1 task id** used to load Studio project context — not the original song `taskId` for account binding. The account from phase 1 is reused.
</Info>

Part of the [Studio Editing](/api-reference/suno/studio) group.
