What is WordPress REST API?

WordPress REST API is an Application Programming Interface (API) that allows external applications to communicate with your WordPress site. This API is based on REST (Representational State Transfer) principles, a common standard for communication between distributed systems on the internet. In the context of website development, REST API allows you to create, read, update, and delete content in WordPress using simple HTTP requests.

The use of WordPress REST API opens up exciting new possibilities for developers. It enables the creation of advanced applications, integration with external systems, and development of more dynamic user interfaces. It can be used to create mobile applications, single-page applications (SPA), or even to connect multiple WordPress sites.

Benefits of using WordPress REST API

Using WordPress REST API brings several significant advantages:

Development flexibility: API allows you to develop front-end applications using any technology you choose, while WordPress serves as a Content Management System (CMS) on the server side.

Improved performance: Applications based on REST API can be faster, as they only transfer the required information and not the entire page.

Easy integration: REST API facilitates integration with external services and applications, expanding the capabilities of your WordPress site.

Faster development: Developers can work simultaneously on the front and back end of the application, accelerating the development process.

How to use WordPress REST API

To start using WordPress REST API, you first need to understand the basic structure of requests. The basic endpoint of the API is usually:

“`
https://yourdomain.com/wp-json/wp/v2/
“`

Then, you can add specific paths for different types of content. For example, to get a list of posts:

“`
https://yourdomain.com/wp-json/wp/v2/posts
“`

You can use various parameters to filter and sort the results. For instance, to get the 5 most recent posts:

“`
https://yourdomain.com/wp-json/wp/v2/posts?per_page=5&orderby=date&order=desc
“`

Security and Authentication

Security is an important consideration when working with WordPress REST API. While some API endpoints are open for public access, others require authentication. WordPress supports several authentication methods, with JWT (JSON Web Tokens) being the most common.

To use JWT, you’ll need to install and activate a plugin like JWT Authentication for WP REST API. Then, you can obtain an authentication token by sending a POST request with your user credentials, and use this token in future requests.

Creating Custom Endpoints

One of the great advantages of WordPress REST API is the ability to create custom endpoints. This allows you to define specific data you want to expose or receive through the API.

To create a custom endpoint, you’ll need to add code to your theme’s functions.php or create a dedicated plugin. Here’s a basic example:

“`php
add_action(‘rest_api_init’, function () {
register_rest_route(‘myplugin/v1’, ‘/author/(?Pd+)’, array(
‘methods’ => ‘GET’,
‘callback’ => ‘my_awesome_func’,
));
});

function my_awesome_func($data) {
$author = get_user_by(‘id’, $data[‘id’]);
if (empty($author)) {
return new WP_Error(‘no_author’, ‘Author not found’, array(‘status’ => 404));
}
$response = array(
‘id’ => $author->ID,
‘name’ => $author->display_name,
’email’ => $author->user_email,
);
return $response;
}
“`

This code creates a new endpoint that returns information about a specific author by their ID.

Common Uses for WordPress REST API

WordPress REST API opens up a wide range of possibilities for content marketing and advanced application development. Here are some common uses:

Creating mobile applications: The API can be used to create mobile apps that display and update content from your WordPress site.

Developing SPA sites: You can build dynamic and fast websites using WordPress as a backend and a JavaScript framework like React or Vue.js as a frontend.

Integration with external systems: REST API allows you to connect your WordPress site to other systems, such as CRM systems or Social networks marketing platforms. This can enable automatic data synchronization and improve operational efficiency.

Creating custom management interfaces: The API can be used to create custom dashboards or management interfaces, which can be more efficient for certain users than the standard WordPress management interface.
