Change the api call to a single api call with a list of keys, rather than many concurrent requests. Then, handle the firebase response

From Claude:

Based on the Firebase Admin SDK types, here are the proper ways to broadcast messages to all users:

Best Approach: Use Topics

The most efficient way to broadcast to all users is using Firebase Cloud Messaging topics:

import * as admin from 'firebase-admin';

const messaging = admin.messaging();

// 1. Subscribe users to a topic (do this when they register/login)
async function subscribeUserToAllUsersTopic(fcmToken: string) {
await messaging.subscribeToTopic(fcmToken, 'all-users');
}

// 2. Broadcast to all users via the topic
async function broadcastToAllUsers() {
const message = {
notification: {
title: 'Broadcast Message',
body: 'This goes to all users!'
},
data: {
customKey: 'customValue'
},
topic: 'all-users' // Send to the topic
};

const response = await messaging.send(message);
console.log('Successfully sent message:', response);

}

Advantages:

• Scalable - no limit on subscribers
• Single API call regardless of user count
• Automatic delivery to all subscribed devices
