In this chapter, you learned how to protect exposed data by enabling a means of authentication and authorization. This is a critical aspect of any publicly available data service. In addition, you learned how to prevent man-in-the-middle attacks using the secured layer transport protocol between a service and its users. As a developer of such services, you should always consider the most appropriate security features that your application should support.

I hope this was a useful experience! You gained enough knowledge and practical experience, which should have made you much more confident in understanding how RESTful APIs work and how they are designed and developed. I strongly encourage you to go through the code evolution chapter by chapter. You should be able to further refactor it, adopting it to your own coding style. Of course, some parts of it can be further optimized, as they repeat quite often. That is an intentional decision rather than good practice, as I wanted to emphasize...
