Firebase Messaging Test Sender

Open this one on your computer, not in the app. Load a service account key and it sends a notification straight to your device.

Credentials

Firebase console → Project settings → Service accounts → Generate new private key. The file is read in your browser and exchanged with Google for a one-hour token. It is never uploaded anywhere and never written to storage, so reloading the tab forgets it.

No key loaded

A service account key does not expire and can push to every user of the project. Use one scoped to a test project, give it only the Firebase Cloud Messaging API Service Agent role, and delete it in the console when you are done testing. Never load a production key here.

Presets

Each preset fills the form and clears every field it does not set.

Destination

Firebase project ID Send to Token or topic name

Message

These fields work on both Android and iOS.

Title Body Image URL shown when the notification is expanded Sound a sound file bundled in the app, without its extension. On iOS the extension is assumed to be .caf — use the iOS section to say otherwise Badge count Collapse key replaces an earlier notification with the same key, without alerting again Deep link page the app opens when the notification is tapped

Android only

An iOS device ignores these.

Status-bar icon an icon bundled in the app, without its extension Accent color 6 or 8 hex digits; the tint is always opaque Channel ID must already exist on the device, or have a Sound set so it can be created Tag replaces an earlier notification with the same tag, and alerts again Priority rarely visible on Android 8 and up — the channel decides whether a notification peeks or makes a sound

iOS only

An Android device ignores these.

Subtitle an extra line between the title and the body Interruption level time-sensitive and critical need an entitlement on the app Sound filename the sound file as bundled on iOS, with its extension. Overrides the Sound field above

Options

High priority — required to wake a closed or dozing app
