Question 119199 in Firebase Question posted in
An extensive official documentation can be found here.

In Firebase Cloud Messaging does Firebase store identical InstanceID of an android/ios device on the cloud?

Does firebase store duplicate copy DeviceID that was generated by the app in google cloud server?

App device InstancesIDs are stored in my Database sent by my app. If firebase stores copy of instanceID how would I get it via API.

    As per the documentation on simple and compound queries.

    import { collection, query, where, getDocs, limit } from "firebase/firestore";

// define query parameters and limit to 1 document (duplicate ID check)
const instanceIDQuery = query(
  collection(db, "collection name here"),
  where("instanceID", "==", "your instance ID here"),
  limit(1)
);

const querySnapshot = await getDocs(instanceIDQuery);
querySnapshot.forEach((doc) => {
  // doc.data() is never undefined for query doc snapshots
  console.log(doc.id, " => ", doc.data());
});

    Make sure you call getDocs asynchronously.

    Based on my understanding, you want to get all the tokens generated by your app from server-side. Currently, there’s no API that can retrieve all registration tokens. You should send and store the tokens to your server upon generation (which you’re doing already).
