+If you're interested in the Web API calling a downstream API, you might want to have a look at the [ASP.NET Core Web API tutorial](https://github.com/Azure-Samples/active-directory-dotnet-native-aspnetcore-v2), in chapter 2 [2. Web API now calls Microsoft Graph/](https://github.com/Azure-Samples/active-directory-dotnet-native-aspnetcore-v2/tree/master/2.%20Web%20API%20now%20calls%20Microsoft%20Graph).
