<?php
function validate_license($licenseKey){
   $license_server = "http://localhost/wpdmpro/";
   $domain = $_SERVER['HTTP_HOST']; // domain name or IP
   $productId = 'PRODUCT_CODE'; // Your Product Code, if you don't add any product code your prouduct, you also can skip it here
   $ch = curl_init();

   curl_setopt($ch, CURLOPT_URL,$license_server); 
   curl_setopt($ch, CURLOPT_POST, 1);
   curl_setopt($ch, CURLOPT_POSTFIELDS, "wpdmLicense=validate&domain={$domain}&productId={$productId}&licenseKey={$licenseKey}");
   // receive server response ...
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
   $server_output = curl_exec ($ch);
   curl_close ($ch);
   return json_decode($server_output);
}
$response = validate_license('1234-1234-1234-1234');
if($response->status == 'VALID') {
 // License is valid
}
if($response->status == 'INVALID') {
 // License is invalid
}
if($response->status == 'EXPIRED') {
 // License is expired
}

?>

{
  "status": "VALID",
  "expire_date": "0",
  "activation_date": "1477958400"
}

  "error" : "ERROR_MESSAGE"
  "expire_date": "1477958400",
  "activation_date": "1477958400"
