Chapter 8Outbound HTTP Requests with Req

Applications rarely exist in isolation. They use APIs (Application Programming Interfaces) to interact with other applications—whether internal or external—to achieve their value. Applications interact with each other in many different ways, but the most common form of interaction is an HTTP-based API. By the end of this chapter, you’ll have what you need to make your own HTTP requests from Elixir.

On the surface, making HTTP requests seems like an easy problem to solve. We pick an HTTP request library, integrate it into our application, and then move on with our day. But the problem is a bit more complex than that. (Don’t worry, the end result will be straightforward.)
