Parameters

id (path) number yes Task ID

Error response example

404 — task not found (or already deleted):

JSON 
{
  "success": false,
  "error": {
    "code": "ENTITY_NOT_FOUND",
    "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.
