Learning WordPress REST API

By: Sufyan bin Uzayr, Mathew Rooney

Overview of this book

The WordPress REST API is a recent innovation that has the potential to unlock several new opportunities for WordPress developers. It can help you integrate with technologies outside of WordPress, as well as offer great flexibility when developing themes and plugins for WordPress. As such, the REST API can make developers’ lives easier. The book begins by covering the basics of the REST API and how it can be used along with WordPress. Learn how the REST API interacts with WordPress, allowing you to copy posts and modify post metadata. Move on to get an understanding of taxonomies and user roles are in WordPress and how to use them with the WordPress REST API. Next, find out how to edit and process forms with AJAX and how to create custom routes and functions. You will create a fully-functional single page web app using a WordPress site and the REST API. Lastly, you will see how to deal with the REST API in future versions and will use it to interact it with third-party services. By the end of the book, you will be able to work with the WordPress REST API to build web applications.

REST architectural constraints

The properties of architecture within REST are realized by applying specific interactions, which will constrain to components, connectors and data elements that can describe applications that are conforming to REST constraints such as RESTful. If any of these constraints are not met, then the application can no longer be considered as a RESTful one. If the compliance with these limitations is achieved, which would be the equivalent of conforming to the REST architectural style, then the system will have non-functional properties such as scalability and performance, simplicity, and portability with further reliability. Under this section, we will cover the formal, known REST constraints in detail.

The formal REST constraints

There are a few formal REST constraints that we will get to know briefly, as follows:

  • Stateless

  • Client-server

  • Layered system

  • Cacheable

  • Code on demand

  • Uniform interfaces

  • Self descriptive messages


The client-server communication is further...
