FCMessaging

C# Implementation of the new HTTP v1 API protocol of Firebase Cloud Messaging (FCM) which is:

the most up to date, with more secure authorization and flexible cross-platform messaging capabilities

Note that if you want to use upstream messaging from your client applications, you must use XMPP

Sending your first message

Before you send your first message you require a credential file given by Firebase:

• In the Firebase console, open Settings > Service Accounts.
• Click Generate New Private Key, and confirm by clicking Generate Key.
• Download and save the file to a secure location

Once you have your server key and credentials, instatiate a client object with:

FCMClient client = new FCMClient("relative-path-to-credential-file");

Create a simle message and send it:

Message message = new Message
  .Builder()
  .ToTopic("news")
  .Title("my title")
  .Body("my body")
  .Build();

string id = await client.Send(message);
