Quick Start Guide

Method 1: Simple Direct Link

<a href="https://verify.nwmd.nl/index.php?age=21&redirect=https://yoursite.com/restricted">
  Verify Age (21+)
</a>

✓ Easiest to implement | ✗ Parameters visible in URL

Method 2: Encoded Parameters (Recommended)

<?php
$params = [
  'age' => 21,
  'redirect' => 'https://yoursite.com/restricted',
  'domain' => 'yoursite.com'
];
$encoded = base64_encode(json_encode($params));
$url = "https://verify.nwmd.nl/index.php?p=" . urlencode($encoded);
?>
<a href="<?php echo $url; ?>">Verify Age</a>

✓ Parameters hidden | ✓ More secure

Method 3: JavaScript Integration

function verifyAge(requiredAge = 18) {
  const params = {
    age: requiredAge,
    redirect: window.location.href,
    domain: window.location.hostname
  };
  const encoded = btoa(JSON.stringify(params));
  window.location.href =
    `https://verify.nwmd.nl/index.php?p=${encodeURIComponent(encoded)}`;
}

✓ Dynamic | ✓ Works with SPAs
