Firebase Notification Tester

Paste firebase-auth.json (service account) → pick a type → send a real FCM push

Send by device token or FCM topic — works for Android, iOS and Web

Your credentials are used only for this request — never stored on the server or in our database.

Your key stays in browser memory for this send only — never stored on the server or in browser storage (cleared on reload). Use over HTTPS on a trusted machine.

Frequently Asked Questions

Is my Firebase service account safe?▾

Your JSON is sent over HTTPS only when you click Send. We do not store it in our database. For extra safety, use a test Firebase project and avoid pasting production keys on shared computers.

Where do I get an FCM device token?▾

From your Android or iOS app using Firebase SDK: log FirebaseMessaging.getToken() (Android) or Messaging.messaging().token (iOS) on a debug build.

Why must data payload values be strings?▾

FCM requires all values in the data map to be strings. Use "123" instead of 123 in your JSON payload.

Can I send to production users?▾

This tool is for internal testing only. Do not use it to spam production users.

Tips & Best Practices

-Use a debug device token from the same Firebase project as your pasted service account JSON
-Start with a simple notification title + body before testing data-only silent pushes
-For Android 8+, set a notification channel ID that exists in your app
-Check the result panel for Firebase message ID and error details after each send
