# Webhooks overview

> How to receive notifications from the Gateway API

Webhooks are sent to the URL configured in the request `callbackUrl` or in the dashboard settings.

Every webhook includes a `token` so you can validate the authenticity of the notification.

## Recommendations

* Respond quickly with a `2xx` status.
* Process heavy tasks asynchronously.
* Validate the received `token`.
* Log received events for auditing.
* Avoid using query endpoints for polling. Prefer webhooks.
