Summary

This chapter showed how to build a REST client using the standard library in Go. We started with some theory about the http package and how we build the Request and Response objects. Finally, we built our REST API client with authentication support and requests for reading and storing data.

The learnings so far get us to the point where we can interact with REST APIs programmatically using Go. The next step is to start building our API.

In the next chapter, we will explore how to design and develop a REST API server in Go using the standard library exclusively.
