RouterOS Scripting

ı want to hotspot add user. I am using a new version device. Could the codes have changed?
these codes are working :
mikrotik.Send(“/ip/firewall/filter/add”);
mikrotik.Send(“=action=drop”);
mikrotik.Send(“=chain=forward”);
mikrotik.Send(“=dst-port=25”);
mikrotik.Send(“=protocol=tcp”);
mikrotik.Send(“=protocol=tcp”);
mikrotik.Send(String.Format(“=src-address={0}”, ip));

mikrotik.Send(“.tag=firewall”, true);

but these codes don’t work :
mikrotik.Send(“/ip/hotspot/users/add”, false);
mikrotik.Send(“=name=999”, false);
mikrotik.Send(“=password=999”, false);
mikrotik.Send(“=profile=profile1”);
