# 2022-10-06: CE - Webhook Event Publishing

### Overview

Webhook Event Publishing is a new platform feature that allows our customers to move towards an event-driven architecture for integrating with other systems. This means that external systems can subscribe to internal events published by the Emporix Platform, such as when an order is created or a price updated. With webhooks, you do not need to call specific API endpoints to look for recent changes in services — you will be automatically notified instead.

| **Event subscription management** | You need to subscribe to events, for example creating or updating a catalog in the Emporix API Catalog Service, to receive notifications about them. You can view existing subscriptions for a tenant.                                                                                                                                                                                               |
| **Event Gateway**                 | The Emporix webhook feature requires you to pre-configure an endpoint on the Event Gateway before you can receive events you have subscribed to. When an event that you subscribed to takes place, a message is sent to the Webhook Service. The service forwards the message to the Event Gateway, which then passes the event to the customer's pre-configured endpoint for this particular event. |
