Unable to create webhook for added/deleted task

Thanks for getting back @Phil_Seeman. The changed filter that I have for a current webhook works fine

"filters": [
            {
                "action": "changed",
                "fields": [
                    "assignee",
                    "due_on",
                    "custom_fields",
                    "name"
                ],
                "resource_type": "task"
            }
        ]

I am unsure how to to alter it to capture task deletions.
