The WordPress REST API provides a RESTful JSON interface for core WordPress data types, permitting the development of modern API-driven web applications within the WordPress ecosystem. I began contributing to the project in early 2014 as a part of my role at Bocoup, where we used the API (initially developed as a stand-alone plugin) in several large-scale projects. In the fall of 2016 I assumed a lead role in the project to manage the effort to merge the API into WordPress itself, resulting in the API’s inclusion in WordPress 4.7—delivering a REST API to 28% of the internet. ((Statistic per w3techs, current as of June 2017.)) I currently serve as the design lead for the REST API focus area, one of the three priority focuses of WordPress core development in 2017.
