REST API Design
Price (without VAT)
Moving in today's world of mobile applications, Internet services, cloud solutions, microservices, and so on, you could not find the concept of REST APIs. They all use them, they all love them, they all have a strong opinion on what is and is not REST. This course will try to get you closer to what their magic is.
First, let's get to know what REST APIs are, where they came from, on which principles they are built. Then we will focus on practical aspects of design and development. We start from the very foundations and gradually work on more complicated issues such as authentication, versioning or security. We will design a simple API together and show how such simple APIs can provide unexpected problems and complications. We will also go through the next phase of the development cycle, testing, deployment and operation. Finally, we will show why it is important to look at APIs as a "first class" product.
