Hello Helen Mamalaki,
Welcome to the Microsoft Q&A and thank you for posting your questions here.
I understand that you have a Line of Business (LOB) app that is not published on the Windows Store, and you are in need of App SID, so that you can complete your set up Windows Push Notification server via Azure Portal as part of Azure Notifications Hubs, included your Android too.
Regarding your question, you can obtain the App SID and Security Key through Azure Active Directory (AAD) / Microsoft Entra integration.
What you need to do are the followings:
- Register your app in Azure Active Directory:
- Go to the Azure Portal.
- Navigate to Azure Active Directory > App registrations > New registration.
- Fill in the necessary details for your app and register it.
- Get the App SID and Security Key:
- After registering your app, go to the Certificates & secrets section.
- Create a new client secret. This will serve as your Security Key.
- The Application (client) ID in the Overview section will be your App SID.
- For setting up Azure Notification Hubs to support Android notifications, you can follow these steps:
- Create a Firebase project:
- Go to the Firebase Console (You can follow this link for tutorial: https://learn.microsoft.com/en-us/azure/notification-hubs/android-sdk
- Create a new project and add your Android app to it.
- Download the google-services.json file and add it to your Android project.
- Configure Azure Notification Hubs:
- In the Azure Portal, navigate to Notification Hubs.
- Create a new notification hub and configure it with the Firebase Server Key obtained from the Firebase Console 1.
