An Exploration of APIs, Versioning, & HTTP

There are Web APIs everywhere, from the classic REST/HTTP, to GraphQL, to gRPC, we rely on them to get things done each and every day. But how much do we think about the design of these APIs? How do you document an API once you've created it? What even is versioning? Do we really understand HTTP? In this episode, Kris and the panel are joined by Jamie Tanna to discuss APIs, their design, how to document them, and more.
