REST vs. GraphQL with Arnaud Lauret and Doc Jones

Over the last two decades, REST has become the de facto standard when it comes to designing Web APIs, as it doesn't require any special initialisation or libraries when working with APIs and offered structured access to resources.

Two key folks from Postman answer this on our third Technology Smackdown, with OpenAPI Lead Arnaud Lauret returning to represent REST and Open Technologies Technical Lead Doc Jones for the GraphQL side.
