The code is:

 // Include the autoloader
 require_once realpath( dirname(__FILE__) . '/Cpanel/Util/Autoload.php');
    
 // Make a configuration data array
 $config=array(
    'service'=> array(
        'whm'=> array(
            'config'   => array(

                'user'=> 'transpas',
                'password'=> 'K05c?@eMpW8]'
            ),

$cp=Cpanel_PublicAPI::getInstance($config);
$accounts=$cp->whm_api('listaccts');
print_R($accounts);
