Application Programming Interfaces

-- Description

In this course, you will learn to understand Application Programming Interfaces, or APIs, as a core aspect of digital architecture. In addition to their use in software architecture, APIs are also used to make business components digitally usable within and between companies. And last but not least, APIs are also designed and offered as products that can be used to earn money directly or indirectly. You will learn about different technologies, their differences and areas of application. We look at the design of APIs in an approach that goes beyond purely technical design. We discuss description languages such as OpenAPI and AsyncAPI and see how they are used within the lifecycle of an API. You will learn what is necessary to use APIs strategically in organizations.
