              $token="AUTHTOKEN";
              $url = "https://crm.zoho.com/crm/private/xml/Leads/getRecords";
              $param= "authtoken=".$token."&scope=crmapi";
              $ch = curl_init();
              curl_setopt($ch, CURLOPT_URL, $url);
              curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
              curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
