Producer Task API

Extend Music

⚠️ Unavailable due to upstream restrictions. Documentation retained for field reference only.

Extend an existing music track from a specified time point. The parent music task must be completed before extending.

CCAPI Task Workflow

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

Availability

  • Official restriction: this Producer action is temporarily unavailable in CCAPI.
  • POST /producer/submit/MUSIC is the only Producer submit action currently enabled.
  • This schema is retained for future reopening after the upstream restriction is lifted.

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
