API not working (Invalid IP ***)

I'm trying this code:

$url = "http://www.mydomain.tld/includes/api.php"; # URL to WHMCS API file
$username = "myadminusername"; # Admin username goes here
$password = "myadminpassword"; # Admin password goes here

$postfields["username"] = $username;
$postfields["password"] = md5($password);

$postfields["action"] = "encryptpassword";
$postfields["password2"] = "aPASSwordIwantTOencrypt";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
$data = curl_exec($ch);
curl_close($ch);

$data = explode(";",$data);
foreach ($data AS $temp) {
 $temp = explode("=",$temp);
 $results[$temp[0]] = $temp[1];
}

if ($results["result"]=="success") {
 # Result was OK!
 echo $results['password'];
} else {
 # An error occured
 echo "The following error occured: ".$results["message"];
}

on many different boxes (even tried on the same box as the one running whmcs) but getting everywhere:

result=error;message=Invalid IP ***.***.***.***

what am I doing wrong?

I just want to integrate my own website letting the users to login with their whmcs data but I do not know which salt you are using so I've to deal with this thing called API (I really wish there was another way to get a password "encrypted"...)

I thought I would just do everything on my own and check if the login was valid with a simple mysql query... but found me in stuck with this damn api thing

yup

result=error;message=Invalid IP 85.x.x.x

Here she is :

When adding an API admin user, the user only needs access to the API. You must also setup the IP(s) you will be connecting from in General Settings > Other. Failure to do this will result in an error Invalid IP

hehehee

Finaly i found, the problem is in documentation,

in the link http://wiki.whmcs.com/API:About is write

When adding an API admin user, the user only needs access to the API. You must also setup the IP(s) you will be connecting from in General Settings > Other. Failure to do this will result in an error Invalid IP

BUT TO CONFIGURE THE IP IS IN THE TAB SECURITY

there is no such thing in general/other in whmcs 4.4.x

Is this correct for allowing a range of  IPS? or is that not supported

I have my IP address to the white list yet I still get this error 

result=error;message=Invalid IP 41.***.***

I am using postman to make my API Call , What I am i not doing correctly?
