PACRP Licensing

Server-side verification using cURL:

<?php
function verifyLicense($key, $domain, $product) {
    $ch = curl_init('https://yourserver.com/verify.php');
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query([
        'license_key' => $key,
        'domain' => $domain,
        'product' => $product
    ]));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $result = curl_exec($ch);
    curl_close($ch);
    return json_decode($result, true);
}

$license = verifyLicense('PACRP-ABCD-1234-EFGH', 'example.com', 'PACRP CAD');
if ($license['success']) {
    echo "License valid! Features: " . implode(', ', $license['features']);
} else {
    echo "Error: " . $license['message'];
}

Simple HTML form with vanilla JS:

<form id="licenseForm">
  <input type="text" id="key" placeholder="License Key" required>
  <input type="text" id="domain" placeholder="Domain" required>
  <select id="product">
    <option>PACRP CAD</option>
    <option>PACRP MDT</option>
  </select>
  <button type="submit">Verify</button>
</form>
<div id="result"></div>

<script>
document.getElementById('licenseForm').addEventListener('submit', async (e) => {
  e.preventDefault();
  const res = await fetch('verify.php', {
    method: 'POST',
    body: new FormData(e.target)
  });
  const data = await res.json();
  document.getElementById('result').textContent = 
    data.success ? 'Valid: ' + data.message : 'Invalid: ' + data.message;
});
</script>

FiveM/RedM server-side verification:
