User notification via xamarin.forms application

Question

As part of a mobile application development project for using library books.

We have developed a Xamarin.form mobile application allowing users to consult available books and make a rental or reservation.

The application works very well except that we want to add a functionality allowing the user to be notified when the reserved book is available.

We would therefore like to set up a notification system, the example of the Whatsapp application illustrates well what we want to do, i.e. when a notification arrives we have the message in the icon bar and we have a number which increments on the application logo. We would like to have ideas for implementing this approach.

NB. the application, even when closed, must be able to display the notification

Hello,

You can do this by Firebase Cloud Messaging.

we want to add a functionality allowing the user to be notified when the reserved book is available.

You can add these users to a firebase notication group, when you want to send notification to them, you can use FCM to send messages to this group.

the application, even when closed, must be able to display the notification.

FCM send notification by the google play services, you can receive this notification when your application is closed.

Best Regards,
