# Mobile Push Notifications API for Angular2 SDK

The Mobile Push Notifications feature connects native PubNub publishing to third-party push services. Supported services include Google Android FCM (Firebase Cloud Messaging) and Apple iOS APNs (Apple Push Notification service).

## Add a device to a push notifications channel

:::note Requires Mobile Push Notifications add-on

```javascript
pubnub.push.addChannels({Array channels, String device, String pushGateway, String environment, String topic},Function callback)
```

| Parameter | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| channels | Array | Yes |  | Channels to enable for push notifications. |
| device | String | Yes |  | Device ID (push token). |
