Existing Amazon Pinpoint resources can be used with Amplify Push Notifications by configuring it with **Application ID** and **Region**.

```js
Amplify.configure({
  Notifications: {
    Push: {
      AWSPinpoint: {
        appId: '<app-id>',
        region: '<region>'
      }
    }
  }
});
```

- **appId**: Amazon Pinpoint application ID
- **region**: AWS Region where the resources are provisioned (e.g. `us-east-1`)
