#Delete task

DELETE /v1/tasks/:id

Deletes a task. A deleted task cannot be restored via the API — create a new one if needed. Together with the task, its comments and time-tracking records become inaccessible.

#Error response example

    "message": "task 999999999 not found"
  }
}

#Errors

HTTP Code Description

#Known specifics

Cascade deletion of nested resources. After a task is deleted, its comments and time-tracking records become inaccessible — a separate DELETE for each of them is not needed. An attempt to access them by the former ID returns 422 BITRIX_ERROR with the message ITEM_NOT_FOUND_OR_NOT_ACCESSIBLE.
