What is WordPress REST API?
The WordPress REST API is a powerful tool that allows developers and users to interact with a WordPress site remotely using HTTP requests. In simpler terms, it lets applications talk to your WordPress website without needing to access the backend interface.
You can:
- Fetch or update content (like posts, pages, or users)
- Manage plugins and settings
- Connect external apps or mobile apps to your site
- Build custom frontends
Why Use the WordPress REST API?
Here’s why learning how to use WordPress REST API is worth your time:
- Headless WordPress: Create a decoupled front-end using React, Vue, or Angular.
- Mobile App Integration: Sync your site with iOS or Android apps.
- Improved Speed & Performance: Fetch only the data you need.
- Automation: Schedule posts, manage users, or trigger workflows programmatically.

How to Access the WordPress REST API
To access the WordPress REST API, you’ll use a URL like this:
https://yoursite.com/wp-json/wp/v2/posts
This endpoint fetches your site’s blog posts in JSON format.
Other common endpoints include:
/wp/v2/pages— Get all pages/wp/v2/users— Retrieve user data/wp/v2/comments— Access comments
How to Use WordPress REST API: Step-by-Step Guide
1. Enable REST API (if not already)
By default, it’s enabled on modern WordPress versions. But make sure:
- Permalinks are set to anything except “Plain”
- You’re not blocking REST access via plugins
2. Make a GET Request
Use your browser or a tool like Postman to test:
GET https://yourdomain.com/wp-json/wp/v2/posts
You’ll see all published blog posts in JSON.
3. Make a POST Request (Create a Post)
You’ll need authentication (more on that below):
POST /wp-json/wp/v2/posts
{
"title": "New API Post",
"content": "This post was created via REST API",
"status": "publish"
}
4. Authentication Options
- Basic Auth (not recommended for production)
- OAuth
- Application Passwords (easy and secure)
🔐 To enable Application Passwords, go to Users > Profile > Application Passwords in WordPress.
Best Use Cases for WordPress REST API
- Creating custom dashboards for editors and writers

- Integrating eCommerce platforms (like WooCommerce)
Tips to Optimize WordPress REST API Usage
