Question

I’m trying to send notifications to user through an app, but they don’t show in any mobile device.

For example, the user makes an action that sends a notification o other user. If he is on a Computer browser he can see the notification, but in iOS/Android/Mobile Facebook the notification don’t show up.

Can you guys help me?

Answer 1

Are you talking about the Notifications API where you make a POST request to /{recipient_userid}/notifications?

If so, this is intended behaviour. From the docs:

Note: Only apps on Facebook.com can use the Notifications API. Also
these notifications are only surfaced on desktop version of
Facebook.com.
