I'm trying push notification with firebase and b4a Ver. 6.0

with filrebase console i can send a push to all devices
or send to single device with token/gcm_id.

can i use a SubscribeToTopic different for each user/devices?

I'm trying to figure out if I can avoid to store gcm_ic/token into my server
and use a unique attribute for my user,
for example the email and send push to all devices that uses.

Thanks

With one account (mail address) you can log in to x devices so FCM doesn't know which one you mean. This is why the token is needed. It's unique for every device. If you need to simplify it by "send a message to Mike" you need to build a reference in a table like you've mentioned.

I have one app where the users need to give a unique nickname to solve the issue with "one user - one mail adrress - 3 devices".

but if i register
1) Mike - device 1 = topic -> mike@domain.com
2) Mike - device 2 = topic -> mike@domain.com
3) Mike - device 3 = topic -> mike@domain.com

can i send a message to Mike using the topic "mike@domain.com"?

To be precise: You can only send Messages to a DEVICE. If you want to use a nickname you Need to map it.


You can send messages

- to the registered devices of a Topic
- to a single device

In your example the message will be sent to all 3 devices (because all subscribed to the same topic)

You can even Register to several topics. The sender decides to which the message is sent to. It's like a Group.
