# MobilePush Custom Keys

To add push notification metadata, such as tracking, to your app, you can use custom keys in MobilePush for Marketing Cloud Engagement.

You can also use custom keys to provide campaign and other tracking data to analytics tools. Another common use of custom keys is to append personalized information about the contact that the app developer can use to alter the app experience. For example, use AMPscript in the custom keys field to look up a user’s loyalty level and append metadata to the message. Custom keys can also be used to pass image URLs with the push notification to allow an app developer to build a carousel of images for a rich push notification.

Note Your mobile app developer must implement custom keys before you can use them.

Once your app developer has implemented custom keys, ask your admin to enable them in your business unit.

1. In the app switcher, hover over your name and click **Setup**.
2. Search for MobilePush.
3. Select the app you want to edit.
4. Select Settings in the dropdown.
5. Under Optional Settings, enable Custom Keys.
6. Enable custom keys.
7. Add the keys for your app.
8. Work with your app developer to configure your custom keys.
