"Coming together is a beginning; keeping together is progress; working together is success."
- Henry Ford
One of the modes of interaction among microservices is direct messaging via APIs. REST APIs are one of the ways to make the direct messaging possible among microservices. REST APIs enable interoperability among microservices irrespective of the technology stack in which they are implemented. In this chapter, we will cover the following topics:
- The concept of REST
- How to define REST URIs with appropriate methods with status codes
- How to use REST-based HTTP URIs using utilities such as cURL
- REST APIs for the Helping Hands application
