 <h3><a class="anchor" href="#notification-encryption" id="notification-encryption" name="notification-encryption"><i class="anchor-icon"></i></a>Notification encryption</h3>
 <p>For FCM and APNS VoIP, an optional encryption key used to encrypt push notifications can be passed to <a href="/method/account.registerDevice">account.registerDevice</a> (<code>secret</code>). This key (<code>auth_key</code>) is used to encrypt the payloads using <a href="/mtproto/description">MTProto v2</a>.</p>
 <p>The FCM payload will be a JSON payload, containing a <code>p</code> field with the base64url-encoded encrypted <a href="/mtproto/description">MTProto payload</a>. After decryption, the result will be a JSON object, prefixed by a 32-bit little-endian integer with the length of the JSON payload. As usual, make sure to follow all security checks as described in the <a href="/mtproto/description#important-checks">MTProto docs</a>.</p>
