Webhook
An HTTP POST request the platform sends to your URL when something happens (order completed, failed, refunded) so you don't need to poll.
A webhook is an outbound HTTP POST from FazerCards to a URL you configure in the dashboard. It carries a JSON payload with the event type (order.completed, order.failed, order.refunded), the order id, and a signed header so you can verify authenticity. Webhooks replace polling — the integration reacts to the event immediately, which is how Telegram bots and storefronts achieve instant delivery to the end customer.
