In this chapter, you have learned how to build Web APIs for your applications for integration purposes and for loosely coupled application architectures.
We have explored different styles for your Web APIs, such as RPC, REST, and HATEOAS. Each of those styles has specific advantages and use cases. You have to choose carefully, depending on your specific application needs, since there is not one single style that outclasses the others.
You have seen examples of how to transform existing controller actions into RPC-style Web APIs and how to build REST-style and HATEOAS-style Web APIs from the ground up.
We have used Postman to manually test our Web APIs and you have acquired enough knowledge to apply all of these new concepts to your own environments.
In the next chapter, we will talk about how to access data by using Entity Framework Core 2 in your ASP.NET Core 2.0 applications.
