Hi

Hi @amirreza mousavi,

Without providing your sensitive details, such as API Identifiers or Usernames/Passwords, could you provide me with a copy of the code you're using?

I can advise if this is the best way to interact with the WHMCS API.

my account user id in the database is 18 but when I run this code that returns nothing.

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://test.com/portal/includes/api.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
    http_build_query(
        array(
            'action' => 'GetContacts',
            // See https://developers.whmcs.com/api/authentication
            'username' => 'apiusername',
            'password' => 'apiPassword',
            'userid' => '18',
            'responsetype' => 'json',
        )
    )
);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
var_dump ($response);
curl_close($ch);

output:

string(71) "{"result":"success","totalresults":"0","startnumber":0,"numreturned":0}"
