WordPress is an open-source content management system (CMS) that makes it easy to create and manage a website. It is the most popular CMS in the world. Millions of business owners, bloggers, and publishers use WordPress every day to maintain their online presence.
The REST API provides public data accessible to any client anonymously, as well as private data only available after authentication. Once authenticated the REST API supports most content management actions, allowing you to build alternative dashboards for a site, enhance your plugins with more responsive management tools, or build complex single-page applications.
