Process description

• From the receiver POV, the app receives and displays the notification on their device, providing relevant information about their order status or other updates.
• From the sender POV, the app sends notifications to users based on their order status or other relevant updates, using SignalR to ensure that notifications are delivered in real-time.

Step-by-step execution plan of the process

• Getting push notifications from receiver POV:
  • Receiver opens the app.
  • The app establishes a connection with the SignalR server.
  • The server sends push notifications to the app.
  • The app displays the notifications to the user.
• Getting push notifications from sender POV:
  • Sender opens the app.
  • The app establishes a connection with the SignalR server.
  • The sender sends a push notification to the server.
  • The server sends the notification to the receivers who are subscribed to that event.

The step-by-step execution of the process is identical to the rateorder process (except that the customer does not rate the order, but simply reads the notification):
