Delete an empty task stage

DELETE /v1/task-stages/:stageId

Bitrix24 REST: task.stages.delete. Scope: task.

Returns 204 without a body. Missing stage: 404. A non-empty stage gives 409 STAGE_NOT_EMPTY (Bitrix24 NO_EMPTY); move tasks out first. Emptiness includes ALL tasks, including those invisible to this key. The first stage gives 409 STAGE_IS_SYSTEM (IS_SYSTEM).

Deletion is irreversible. Group stages require owner/moderator rights. Your own My Plan stages can also be deleted under these rules.

Example

Terminal 
curl -X DELETE "https://vibecode.bitrix24.com/v1/task-stages/11" \
  -H "X-Api-Key: YOUR_API_KEY"

Writes require a READWRITE key. No automatic retry after timeout: reread the object before retrying. Bitrix24 permission refusals return 403; other business refusals return 422.
