# Push Callbacks

Netmera provides the following push notification callbacks:

* **Push Register**: Triggered when a device registers for push notifications.
* **Push Receive**: Triggered when a push notification is received.
* **Push Open**: Triggered when a user taps the notification.
* **Push Dismiss**: Triggered when a user dismisses the notification.
* **Push Button Click**: Triggered when a user interacts with a button inside the notification.
* **Carousel Object Select**: Triggered when a user selects an item in a carousel notification.

To enable these callbacks in your React Native project, follow the steps below:

### Step 1: Create `NetmeraPushHeadlessTask.js`

* Create a new file named `NetmeraPushHeadlessTask.js` in your React Native project and define the callback functions:

```javascript
export const onPushRegister = async (message) => {
    console.log("onPushRegister: ", message);
};

export const onPushReceive = async (message) => {
    console.log("onPushReceive: ", message);
};

export const onPushOpen = async (message) => {
    console.log("onPushOpen: ", message);
};

export const onPushDismiss = async (message) => {
    console.log("onPushDismiss: ", message);
};

export const onPushButtonClicked = async (message) => {
    console.log("onPushButtonClicked: ", message);
};

export const onCarouselObjectSelected = async (message) => {
    console.log("onCarouselObjectSelected: ", message);
};
```

### Step 2: Initialize `NetmeraBroadcastReceiver` in `index.js`

* In your `index.js` file, import the callback functions and initialize `NetmeraBroadcastReceiver`:

```javascript
import {
    onCarouselObjectSelected,
    onPushButtonClicked,
    onPushDismiss,
    onPushOpen,
    onPushReceive,
    onPushRegister
} from "./NetmeraPushHeadlessTask";

Netmera.initBroadcastReceiver(
    onPushRegister,
    onPushReceive,
    onPushOpen,
    onPushDismiss,
    onPushButtonClicked,
    onCarouselObjectSelected
);

// Ensure this is called after `Netmera.initBroadcastReceiver`
AppRegistry.registerComponent(appName, () => App);
```
