Device Fingerprint Verification API Documentation

It may be necessary to ensure that the user hasn't tampered with results after passing through a JavaScript redirect. We offer a simple API that can retrieve the results server side. Requests to this API and all reporting APIs will not consume an API lookup credit.

Verifying Results

To start you'll want to use the "Fetching Results" code from the Device Fingerprint Documentation. Please pass the device ID to your server via Ajax or append the value to a hidden form element. Upon a successful "Fetching Results" request, you can make a GET/POST request to the URL below. Please replace "API_KEY", "USER_IP_HERE" and "DEVICE_ID_HERE" with their respective values.

<?php
// Get the end user's IP.
$user_ip = $_SERVER['REMOTE_ADDR']; // $_SERVER['HTTP_CF_CONNECTING_IP'] if using cloudflare.

// Get the device ID from our device tracker request.
$device_id = isset($_REQUEST['id']) ? $_REQUEST['id'] : null;
	
// Generate our URL.
$url = sprintf('%25s-2.html', $api_key, $user_ip, $device_id);

// Get JSON result.
$json = file_get_contents($url);
	
// Decode the result
$result = json_decode($json, true);

if(isset($result['success']) && $result['success'] === true){
	if(isset($result['id'])){
		if($device_id === $result['id']){
			// Request was valid. You can also use $request['fraud_chance'] here.
		}
	}
} else {
	// Something went wrong.
}

# THIS SHOULD NEVER BE USED IN PRODUCTION AS IS!
