API stands for Application Programming Interface. An API is a software intermediary that allows two applications to communicate and exchange data. It is one of the main drivers of our world of communication as we know today.

API documentation is a technical content deliverable, containing instructions about how to effectively use and integrate with an API. It’s a concise reference manual containing all the information required to work with the API, with details about the functions, classes, return types, arguments and more, supported by tutorials and examples.
