DESCRIPTION
Application developers are the customers of your API. Success is measured by how quickly those developers enjoy success using your API in their applications. And rapid adoption of an API by your internal, partner, or external developers is all about design. Building upon their prior work in API design, Marsh Gardiner and Brian Mulloy unveil RV, a style of API design that embraces developer adoption as its guiding principle. They explore the constraints and opportunities introduced by RV and discuss RV's place in the context of other design approaches like REST and Hypermedia. See the youtube video of this webcast https://www.youtube.com/watch?v=u-bGz9HQIuo
