# Overview

When integrating with PaySway, you often need your applications to respond automatically whenever important events occur. This is where webhooks come into play. Instead of constantly polling for updates, you can rely on PaySway to send notifications to your systems in real time whenever new activity happens.

## How webhooks work

A webhook is a secure HTTPS endpoint that you host within your backend. When events occur in PaySway, we send HTTPS requests containing JSON payloads to your registered endpoints. Each payload includes information about what happened and when.
