WordPress now includes a full featured REST API with default routes for content and the ability for plugins to add additional routes. This provide new ways to read and write data on your WordPress sites that is perfect for use with JavaScript-driven interfaces, apps and more. But do you know what exactly what is available and how to use each route? Every WordPress site is unique, so every site’s REST API will be different. In this talk you will learn how to use route discovery to learn the answers to each of these questions, for every site. CalderaForms.com/wclax2017
