FcmSharpClient 1.0.0

Firebase Messaging Client for C#

This is a C# library to send messages via FCM directly to known device tokens. If this doesn't make sense to you, this library is not for you.

Usage

To use the FcmClient you require the FCM Api-Key, which you can get from your Firebase console: https://console.firebase.google.com/project/(your-project-id)/settings/cloudmessaging

You will also need to create an HttpClient and manage its lifecycle by yourself.

var httpClient = new HttpClient();
var fcmConfiguration = new FcmConfiguration("YOUR-API-KEY");
var fcmClient = new FcmClient(fcmConfiguration, httpClient);

With the FcmClient ready you can now send a message directly to one or more known device tokens.

try {
    var sendResult = await fcmClient(new string[]{ "fcm_token" }, 
      "displayed title", "displayed message", // both visible when the app receives the push message
      new { key = "value" } // an optional json serializable object that can be processed by your app
    );
  foreach (var failedToken in sendResult.failedSends) {
    // clean up failed tokens
  }
}
catch (FcmSendException) {
  // can and will occurr for invalid api keys or failed http connections
}
