By adding custom content (image or video), you can give a unique touch to your notification. 

1. Create a new Notification.

2. Select the language and storefront for your notification, the content link and the title and subtitle. 

3. Click on the pencil icon on the top right of the preview.

4. Select Video or Image and upload your content.

Both Video and Image can be uploaded in any dimension. The content automatically scales to the users phone. The only requirement is that the video placeholder has the same dimensions as the video. The placeholder makes sure that an image will be shown when the video is still loading, so your customer doesn't see a blank notification. 

5. Your notification is now ready to be send, with your custom content. Don't forget to test your notification!
