Space is a team tool that integrates chats, meetings, git hosting, automation, and much more. It has a HTTP API that lets you integrate third party apps and workflows. That API is huge, though! In this session, we will not spend too much time talking about Space. Instead, we'll focus on itsAPI. We'll look at the process, thought and technology behind the Kotlin SDK for Space, and how we make that massive API more digestible. You will see how we used code generation, domain-specific language, and how building extensibility for third-party developers means you will have to guide them into the pit of success.
