How to send firebase notifications to audience via HTTP

firebaser here

There is currently no way to send a notification to a user segment programmatically. It can only be done from the Firebase Console as you've found.

We're aware that allowing this through an API would expand the potential for Firebase Notifications a lot. So we're considering adding it to the API. But as usual: no commitment and no timelines, since those tend to change as priorities shift.

This has been a popular request, but unfortunately it is not yet possible. We are looking into this. Please check Firebase Cloud Messaging announcements for any updates in the future.

You can try with topic subscriptions. It is not perfect solution but the best for me at this time.

{
  "to": "/topics/audience1_subscription"
  "data" : {
     "title" : "Sample title",
     "body" : "Sample body"
   },
 }
