The WordPress Rest API also makes it possible for WordPress websites to get rid of the default WordPress admin interface to offer a completely personalized admin or content experiences using a diverse technology stack.

Calypso – WordPress’ desktop app – is a beautiful example of this. Calypso is built using a single Javascript application that uses the WordPress REST API to communicate between WordPress.com and the core.

Because the WordPress REST API is now an integral part of WordPress core, it is important the developers get a good handle on how it works and the new possibilities it opens up for interacting with WordPress.wordpress rest API

A primer on the WordPress REST API

let’s first understand the term a little better.

So what does API stand for?

API stands for Application Program Interface.

In simplest terms, it’s a means of communication between two different applications.

A common example of an API in action is the Tweet Deck that a lot of websites display. Displaying this Tweet Deck becomes possible via an API where the website just pulls data from Twitter and displays it.

What about REST?

REST is short for REpresentational State Transfer.

REST is an HTML-based architectural style of building APIs. A RESTful architecture uses HTTP requests to post, read, update, and delete data between two sources.

So when we talk of a REST API, we essentially mean an API that uses HTML methods to communicate.

And what about JSON?

The WordPress REST API is the same format as the WordPress JSON REST API.

JSON (or Javascript Object Notation) is a minimal, text based data-interchange format that’s used to seamlessly exchange data between different platforms (even if the platforms use different languages).

JSON is a lightweight alternative to XML-based solutions, making it perfect for mobile apps with bandwidth limitations.

Why use the WordPress REST API

You might be wondering about what’s so exceptional about the WordPress REST API and why you should care about it.

Well … the WordPress REST API empowers you to do more with WordPress.

For example:

  1. Write applications in any language you know and make it interact with a WordPress site (the only 2 requirements being that your app’s language should use HTML methods and be able to interpret JSON)
  2. Design completely personalized admin and content experiences
  3. Develop Single Page Applications on top of WordPress

And much more.

It’s almost impossible to list down all the potential applications/interfaces/experiences that can be created with the REST API. WordPress’ REST API handbook rightly says:

Our imagination is the only limit to what can be done with the WordPress REST API. The bottom line is, if you want an structured, extensible, and simple way to get data in and out of WordPress over HTTP, you probably want to use the REST API.

But I know implementation is always much more difficult than understanding theory. For Development of WordPress Rest API Contact us now.
