Talking to 25% of the web
A WordPress REST API White Paper by Human Made

An in-depth report and analysis on the WordPress REST API

The WordPress REST API is one of the latest features of WordPress, the content management system used by 25% of the web. The API exposes data in WordPress, making it available for developers to use in different contexts, and making it possible to use WordPress as a headless CMS.

At Human Made, we have experience using the REST API in our own products and on client projects. Employees at Human Made include Ryan McCue, the co-lead of the WordPress REST API project, and Joe Hoyle, who is a member of the team.

We’ve used all of this internal knowledge to produce Talking to 25% of the Web: An in-depth report and analysis on the WordPress REST API.
