# Getting started

This topic provides an overview on how to get started with the Connectivity Notification Service (CNS).

## Prerequisites

In order to start consuming notifications, you need to:

- Have an endpoint that can receive notification webhooks
- Have an endpoint that serves JWTs for authenticating Booking.com API requests. For more details on the authentication setup, see  [Setting up authentication](/connectivity/docs/notification-service/authentication)


## Integration steps

**Step 1**: Set up an HTTPS endpoint to serve JWTs.

**Step 2**: Set up a HTTPS endpoint to receive and process notifications.

**Step 3**: Register your endpoint and share the API authentication credentials with Booking.com using the [Provider Portal.](https://connect.booking.com/api-notification-configuration) For more information on how to set up the configuration, see [Configuring Notification Service.](/connectivity/docs/notification-service/configuring-notification-subscriptions)
