Now that we are clear about what HTTP is and the building blocks behind it, we need to design a friendly and robust API. Another advantage of this is that we will improve the developer experience in our organization by having a well-defined API.

API documentation is another key practice that you have to apply in every API development you will do. With documentation, the development team and API consumers are aware of the full functionality of the API, because they are defined in an easy-to-read format. For example, the financial team and the logistics team in an organization can share their API documentation between them and start working on a possible integration solution immediately because they now know the full details of the APIs.

Let's learn how to design robust APIs by understanding the API first movement and other design concepts.
