 ## Add notifications to your mobile app
 
 Azure Communication Services integrates with [Azure Event Grid](../../../../../event-grid/overview.md) and [Azure Notification Hubs](../../../../../notification-hubs/notification-hubs-push-notification-overview.md), so you can [add push notifications](../../../../concepts/notifications.md) to your apps in Azure. You can use push notifications to send information from your application to users' mobile devices. A push notification can show a dialog, play a sound, or display an incoming call UI.
