# Delete Assignment Rule
This call is used to delete an assignment rule. Care should be taken when using this call, as there will be no prompt (‘are you sure you want to delete this rule?’) when it is sent. The deletion request will be immediately processed.
It is sent as a DELETE call, and the url includes the ID (from the ‘get assignment rules’ call) for the rule to be deleted.

}
}
```
