# Webhooks

> Learn how to listen to events whenever certain actions occur on your account.

### Overview

Webhooks are used to communicate updates on transaction initiated with our API or SDK. For every transaction initiated, a POST request is sent to the designated Webhook URL with information about the event transactions.

### Security

All Webhook requests are sent with a bridge-webhook-secret header for verification. It should match the secret you passed when creating the webhook.
