<h4>API reference</h4>
<p>This plugin includes a working serial validation API for locally created serials:</p>
<pre><code>POST https://yourdomain.com/wp-json/wc-custom/v1/validate-serial
</code></pre>
<p>Required fields:</p>
<ul>
<li><code>serial</code> – the license key shown to the customer.</li>
<li><code>hardwareId</code> – one stable activation identity.</li>
</ul>
<p>For websites, WordPress plugins, or PHP apps, use the canonical site URL as <code>hardwareId</code>.</p>
<p>For desktop software, use a stable hashed device ID as <code>hardwareId</code>. Do not send raw hardware serial numbers.</p>
<p>Example JSON request:</p>
<pre><code>{
  "serial": "ABCD-EFGH-IJKL-MNOP",
  "hardwareId": "https://example-client-site.com"
}
</code></pre>
<p>Example success response:</p>
<pre><code>{
  "valid": "True",
  "message": "Serial validated and hardware ID activated.",
  "email": "customer@example.com",
  "last_name": "Customer"
}
</code></pre>
<p>Common failed responses use <code>"valid": "False"</code> with a <code>message</code>, for example serial not found, hardware ID mismatch, expired, suspended, or rate limited.</p>
<p>Important: this plugin validates serials created inside Codulon Serial Manager Lite. The separate full version uses the same endpoint path but validates WooCommerce serials, subscriptions, renewals, revoked access, customer order data, and advanced license rules.</p>
