# Push Notification - Device Token

{% hint style="warning" %}
[Personalized Push Notification](/integrations/personalized-push-notification.md) feature must be enabled to use this JS Bridge.
{% endhint %}

We’ve provided the JavaScript function `twinr_push_token_fetch()` to make it easy for you to fetch the device token along with the platform type (Android or iOS).

To fetch the device token, simply call the `twinr_push_token_fetch()` function from your website’s JavaScript.

```javascript
await twinr_push_token_fetch();
```

The function returns a JSON object with two fields:

* token: The unique device token required for push notifications.
* platform: The platform of the user’s device, which will be either "android" or "ios".

Example of a typical response:

```json
{
  "token": "abc123def456ghi789",  // Example device token
  "platform": "ios"               // or "android"
}
```
