Overview of this book

REST is an architectural style that tackles the challenges of building scalable web services. In today's connected world, APIs have taken a central role on the web. APIs provide the fabric through which systems interact, and REST has become synonymous with APIs. The depth, breadth, and ease of use of ASP.NET Core makes it a breeze for developers to work with for building robust web APIs. This book takes you through the design of RESTful web services and leverages the ASP.NET Core framework to implement these services. This book begins by introducing you to the basics of the philosophy behind REST. You'll go through the steps of designing and implementing an enterprise-grade RESTful web service. This book takes a practical approach, that you can apply to your own circumstances. This book brings forth the power of the latest .NET Core release, working with MVC. Later, you will learn about the use of the framework to explore approaches to tackle resilience, security, and scalability concerns. You will explore the steps to improve the performance of your applications. You'll also learn techniques to deal with security in web APIs and discover how to implement unit and integration test strategies. By the end of the book, you will have a complete understanding of Building a client for RESTful web services, along with some scaling techniques.

Client-based API-consumption architecture

We have discussed RESTful Services, Web APIs, as well as how to register, authenticate, and authorize a user. Moreover, we did focus a little on the consumption aspect of the service. Services are designed not only to test on Postman but actually for consumption by different types of application (desktop, web, mobile, smart watches, and IoT apps).

While most modern apps are based on MVC-based architecture, there is a certain need to consume web services inside the controllers of those apps. Basically, I need to find a way to call the services from my controller without any hassle.

For that to happen, I can't call Postman or any other third-party tool. What I need is a client or component that can interact with the RESTful Web API for me. I just need to tell that client that I need the Customer details by passing the id or some identifier...
