# Getting started with Yandex Cloud Notification Service

{% note info %}

The service is at the [preview stage](../overview/concepts/launch-stages.md).

{% endnote %}

To enable Cloud Notification Service, request access to the service from your account manager or [technical support](https://center.yandex.cloud/support).

Cloud Notification Service (CNS) is a service for multichannel notifications of users. The service's HTTP API is compatible with the [Amazon SNS API](https://docs.aws.amazon.com/sns/latest/api/welcome.html).

At the Preview stage, you can send [push notifications](concepts/push.md) to iOS and Android devices, browsers, and via [SMS](concepts/sms.md). Notifications can go both to individual endpoints and endpoint groups via [topics](concepts/topics.md).

Moving forward, we will be adding notifications to messengers.

Get started with [push notifications](quickstart-push.md) or [SMS](quickstart-sms.md).
