Tasks - Delete Task

Service:
Batch Service
API Version:
2025-06-01

Deletes a Task from the specified Job.
When a Task is deleted, all of the files in its directory on the Compute Node where it ran are also deleted (regardless of the retention time). For multi-instance Tasks, the delete Task operation applies synchronously to the primary task; subtasks and their files are then deleted asynchronously in the background.

DELETE {endpoint}/jobs/{jobId}/tasks/{taskId}?api-version=2025-06-01
With optional parameters: 
DELETE {endpoint}/jobs/{jobId}/tasks/{taskId}?api-version=2025-06-01&timeOut={timeOut}
