Push notifications from server side of the app

User_101

I have implemented push notifications to my app using firebase console. Now what I would like to do is, trigger the push notification at my server side.

For eg: when new user signs up, I want to trigger the notification from server. How can this be done

Here is a guide which provides a step-by-step explanation of how to use Firebase Cloud Messaging to implement remote notifications (also called push notifications) in a Xamarin.Android application.

Before pushing messaging, the client app must first register with FCM. When the app server sends a downstream message to the client app, it uses the following steps as enumerated in the above diagram:

• The app server sends the message to FCM.
• If the client device is not available, the FCM server stores the message in a queue for later transmission. Messages are retained in FCM storage for a maximum of 4 weeks.
• When the client device is available, FCM forwards the message to the client app on that device.
• The client app receives the message from FCM, processes it, and displays it to the user.
