How do you build a powerful and secure API using ASP.NET? In this course, Using OAuth to Secure Your ASP.NET API, you'll learn how to use ASP.NET and OAuth together to create an API that is highly secure and well-built. You'll start off by looking at an insecure and badly-designed ASP.NET API, talking about how to approach this API from third party applications, and also how to consume this API internally. You will then examine the benefits of choosing different OAuth flows for different scenarios. Finally, you'll see how you can use IdentityServer to protect your API. At the end of this course, you'll have the skills you need to be able to build APIs that are a lot more secure.
