how to Cancel placed orders

Cancel Order doesn't seem to work. Although I can place an simple order with this API, unable to cancel is a deal breaker.

Called order_list to get orders, then sending id of an active order to "https://api3x.firstrade.com/private/cancel_order", request got rejected by server.
{"statusCode":404,"error":"Not Found","message":"Not Found"}

	data = {
	"order_id": order_id,
	}
	response = self.session._request("post", url=urls.cancel_order(), data=data)
