What is the WordPress REST API?

The WordPress REST API, created by Human Made’s Ryan McCue, facilitated a major evolution, exposing WordPress content and data as JSON via a standardised RESTful API. For the first time, data was unlocked, and an explosion in the number and complexity of WordPress integrations began.


Download the guide and dive into what the WordPress REST API is, why it’s RESTful, what makes it open and why the REST API allows for a more powerful experience in:

  • Using WordPress as part of a complex multi-service workflow
  • Separating frontend delivery from the CMS
  • Powering multiple frontends from the same content

Why did award-winning digital studio ustwo choose the WordPress REST API?

Creating a custom API for content delivery with a React frontend and WordPress backend sounds complex, but our experience with the REST API made it all possible.

To fulfil our design ambitions we decided to build our frontend as a single-page application, which was made possible with the WP-API.
