I use a Mikrotik API, i can use add Command but I do not know how can use remove command.
example Adding VPN user:
$API->comm("/ppp/secret/add", array(
"name" => "user",
"password" => "pass",
"remote-address" => "172.16.1.10",
"comment" => "{new VPN user}",
"service" => "pptp",
));
Now how can Remove example VPN User1?
