8. Creating and Using Web API Clients

Overview

In this chapter, you will step into the world of HTTP practice by making calls to Web APIs. You will interact with Web APIs in a variety of ways using a web browser, your own HTTP client, and NuGet packages. You will learn the basics of security involved in Web APIs, use PayPal to make sandbox payments, and explore cloud services such as Azure Text Analytics and Azure Blob storage.

By the end of this chapter, you will be able to read HTTP requests and response messages, make calls to any Web API, and create your own HTTP client to simplify your work with complex APIs. You will also be able to dissect and learn both incoming HTTP requests and outgoing HTTP responses in any form and use development tools in the Chrome browser to inspect traffic moving back and forth when browsing your favorite websites.
