Suno Task API

Extend Music

Extend an existing song from a specific timestamp. The new section seamlessly continues from the continue_at point.

CCAPI Task Workflow

  1. Submit -> POST /suno/submit/EXTEND -> {"code":"success","data":"task_xxx"}
  2. Fetch -> GET /suno/fetch/{id} or POST /suno/fetch -> inspect data.status and data.data
  3. Complete -> when data.status = "SUCCESS", data.data contains the normalized result payload

Notes

  • Authenticate with Authorization: Bearer <CCAPI token>
  • Submit endpoints always return the public task_xxx ID instead of exposing the upstream job ID
  • Fetch endpoints return the persisted CCAPI task record (TaskDto) with normalized data payload
post/suno/submit/EXTEND
