I am using Cloudflare Workers which are not fully compatible with NodeJS. I am already able to send notifications using token and the REST API:

I have an app, which is registered with one or more firebase projects, the first of which is static, while all others are dynamically added as needed.
This seems to work fine on the app side.

The Java Android app receives a FCM and write a value to Firebase. Sometimes this value does not immediately appear in the Firebase console. It always appears eventually.

I need clarification regarding the terms and conditions for using FCMv1 for enterprise applications. We are developing an app for our business that will soon be available on the Play Store. Can we register the app with Firebase and use FCMv1 for free without violating any terms of use?

I am updating a system that uses the legacy FCM APIs to the new HTTP v1 API: https://firebase.google.com/docs/cloud-messaging/migrate-v1?hl=en&authuser=0. The only functionality we are using is messages sending.

I want to validate the FCM Tokens like 500 FCM tokens. I know how to validate single fcm token using below api :-

I used two different code structures for phone notification.
