1# Push Notification Sender
2
3This val can be used in other vals to send notifications to a segment using [OneSignal's REST API](https://documentation.onesignal.com/reference/create-notification)
4
5This is really handy if you want to send push notifications to your phone without building a native app! I built a barebones React PWA that asks for a password then loads the OneSignal Web SDK that I deployed to [Netlify](https://www.netlify.com/) for free. OneSignal has [easy to follow docs](https://documentation.onesignal.com/docs/web-sdk-setup) so you can build this functionality into a React, Angular, Vue app or even Wordpress! Then [install the PWA](https://www.bitcot.com/how-to-install-a-pwa-to-your-device/) on your platform of choice and you're off to the races!

18- Add more metadata from the Djehuty API response.
19
20Limitations:
21
22- This is a temporary workaround until the Presentation API is implemented as part of Djehuty
23- Only images are currently supported (not video/audio)
24- The val needs to do some API requests before producing the manifest and doesn't cache responses
