Send Push Notifications From .NET 6 Application To Firebase Using The Firebase Cloud Messaging API


This article will teach us how to send push notifications from a .NET 6 application to Firebase using the FirebaseAdmin SDK for .NET.

What are Push notifications?

Push notifications are essential for any modern mobile or web application to engage and retain users. Firebase Cloud Messaging (FCM) is a popular platform that allows you to send push notifications to users on Android, iOS, and the Web.


Before we begin, make sure you have the following.

  • A Firebase account and a Firebase project set up.
  • A .NET 6 application with the FirebaseAdmin SDK for .NET installed.
  • You can use a Firebase service account key file to authenticate your .NET application.

Step 1. Install the FirebaseAdmin SDK for .NET

The FirebaseAdmin SDK for .NET allows you to interact with Firebase services from your .NET 6 application. You can install it using the following command in the Package Manager Console:

dotnet add package Google.Cloud.FirebaseAdmin

Step 2. Authenticate the FirebaseAdmin SDK

To use the FirebaseAdmin SDK, you need to authenticate it with your Firebase project's service account key. You can do this using the following code:

using Google.Apis.Auth.OAuth2;
using Google.Cloud.FirebaseAdmin;

FirebaseApp.Create(new AppOptions()
    Credential = GoogleCredential.FromFile("path/to/your/service/account/key.json"),

Note. Replace "path/to/your/service/account/key.json" with the path to your Firebase project's service account key file.

Step 3. Send Push Notifications

Now that you have authenticated the FirebaseAdmin SDK, you can use it to send push notifications to your users.

using FirebaseAdmin.Messaging;

// Construct the message payload
var message = new Message()
    Notification = new Notification
        Title = "Test Notification",
        Body = "This is a test notification"
    Token = "your_device_token"

// Send the message
var response = await FirebaseMessaging.DefaultInstance.SendAsync(message);
Console.WriteLine($"Successfully sent message: {response}");

Note. Replace "your_device_token" with the device token for the device you want to send the push notification.

The Message object contains the notification message you want to send, and the Token property identifies the device you want to send it. Once you have constructed the message, you can use FirebaseMessaging.DefaultInstance.SendAsync() method to send it to Firebase.


This article taught us how to send push notifications from a .NET 6 application to Firebase using the FirebaseAdmin SDK for .NET. With this knowledge, you can engage your users and inform them about important events in your application. Hope this article will help the readers.

Happy Coding!!!
