Code Sample C# Azure Functional App to Get Entra Id Users and Groups using MS Graph API v5.x

Complete Code Sample on GitHub

You will need to setup a Functional App in Azure and register the app in Entra Id setting the permissions to Call the Graph API with User.Read and Groups.Read permissions. Then create an Azure KeyVault to store the secret Key. Calls Microsoft Graph API v5.x Azure Functional App in .Net Core V8 Multi-Tenant support Async Methods to get Entra Id (AAD) User(s) Async Methods to get Entra Id (AAD) Group(s) Uses Azure Key Vault to secure Secrets Uses Managed Identity
