Payment Webhook

Category: infrastructure

An automated, event-driven HTTP notification sent from the payment processor to your application when a status changes (e.g., charge succeeds).

Webhooks are the asynchronous "callback" mechanism of finance. Because payment processing is slow, the gateway doesn’t wait for your server; it processes the charge and then "pings" your webhook URL. Your application must listen for these signals to update order statuses or unlock digital goods.

Common Examples

• Our backend must have a robust webhook handler to acknowledge the payment-success signal and automatically trigger the fulfillment workflow.
• A failed payment webhook configuration can lead to "orphan orders" where the money is collected but the platform fails to provision the user’s service.
