Firebase: Get list of users subscribed to a topic

Question

Is there a way to, using the Firebase Admin SDK for Java, get a list of all registration tokens that are subscribed to a given topic?

If not, is there a way to get that information using the REST API?

Answer 1

There is no API to get a list of the tokens that are subscribed to a specific topic.

See:

• Count subscribers of a topic in Firebase Cloud Messaging
• How to know whether a user has subscribed to a topic in FCM?
• List of clients who have registered for a topic in FCM
