# Updated network token

<a href="https://docs.solidgate.com/payments/integrate/webhooks/" target="_blank">Webhooks</a> provide merchants with real-time notifications when the network token associated with a payment card is updated by Visa or Mastercard. These notifications allow merchants to automatically update their systems based on the events.
<blockquote>
<p>Duplicate webhook events can occur. Implement <a href="https://docs.solidgate.com/payments/integrate/webhooks/#event-handling" target="_blank">idempotency</a> on your end to avoid processing the same event twice.</p>
