How to send firebase notifications to audience via

问题:

In Firebase Console I set up audiences based on various user properties and now am able to send notifications to different user segments via console. Is there a way to do the same by http requests to fcm servers? There should be a trick with "to" field, but I couldn't figure it out.

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"
   },
 }

Yes.There is trick with the "to" field as mentioned in below.

web URL is: https://fcm.googleapis.com/fcm/send

Content-Type: application/json

Authorization: key="YOUR_SEVER_KEY"

JSON DATA FORMAT:

{"to": "USER_FIREBASE_TOKEN",

"data": {"message": "This is a Firebase Cloud Messaging Topic Message",}

"notification": {"body": "This is firebase body",}}";
