I have created a small App that's able to receive Push Notifications from the FCM Console.
What i want to do now is to send a Push-Notifications to all Android Phones that got the app Installed using the API. And this is where i got completely lost.
Is there no way to send it to all Phones without collecting all the registration-ids?
Does this only work with the Console but not with the API?
thanx in advance
