How to Create a Headless WordPress Site

This guide walks you through how to create a headless WordPress site using WordPress as a content management backend while delivering content via APIs to a custom front end. You’ll learn setup, API configuration, and front-end integration—no coding expertise required.

Key Takeaways

  • Headless WordPress separates the backend from the frontend: WordPress manages content, while a modern framework like React or Vue handles the user interface.
  • WordPress REST API is essential: It allows your front-end app to fetch and display content dynamically from your WordPress dashboard.
  • Choose the right front-end framework: React, Next.js, or Gatsby are popular choices for building fast, scalable headless sites.
  • Performance and SEO improve significantly: Static site generators and modern frameworks enhance speed and search engine visibility.
  • Security and scalability increase: Decoupling reduces attack surfaces and allows independent scaling of front and back ends.
  • You can reuse content across platforms: The same WordPress backend can power websites, mobile apps, and digital kiosks.
  • Plugins and themes still work—but differently: While traditional themes are disabled, plugins that enhance the REST API remain useful.

What Is a Headless WordPress Site?

A headless WordPress site uses WordPress as a content management system (CMS) but removes the traditional front-end “head”—the theme layer. Instead, content is delivered via the WordPress REST API to a separate front-end application built with tools like React, Vue, or Next.js. This setup gives developers more flexibility, better performance, and improved security.

Think of it like this: WordPress becomes your content engine, and your custom-built website or app becomes the display. You still use the familiar WordPress dashboard to write posts, upload images, and manage users—but your visitors never see the classic WordPress theme.

Why Go Headless?

There are several compelling reasons to create a headless WordPress site:

  • Faster load times: Modern front-end frameworks optimize performance with techniques like static site generation.
  • Better developer experience: Front-end developers can use their preferred tools without being limited by WordPress themes.
  • Multi-platform content delivery: Use the same content for websites, mobile apps, smart displays, and more.
  • Enhanced security: With no front-end theme, there are fewer vulnerabilities exposed to hackers.
  • Future-proof architecture: Easily upgrade or change the front end without touching the content backend.

Step 1: Set Up Your WordPress Backend

The first step in creating a headless WordPress site is setting up a standard WordPress installation. This will serve as your content hub.

Install WordPress

You can install WordPress on any hosting provider that supports PHP and MySQL. Popular options include SiteGround, Bluehost, or WP Engine. Follow your host’s one-click installer, or manually upload WordPress files via FTP.

Choose a Minimal Theme (Optional)

Since the front end won’t use the theme, you can install a lightweight theme like Twenty Twenty-Four just to keep the admin area functional. Alternatively, you can deactivate the theme entirely if you’re comfortable managing WordPress without one—though this is not recommended for beginners.

Install Essential Plugins

Even in a headless setup, plugins can enhance your API. Consider installing:

  • WP REST API (already built-in since WordPress 4.7): Enables content access via API endpoints.
  • JWT Authentication for WP REST API: Adds secure authentication for private content.
  • ACF to REST API: Exposes Advanced Custom Fields data through the API.

Step 2: Enable and Test the REST API

WordPress comes with a built-in REST API that lets external apps fetch content. Let’s make sure it’s working.

Access the API

Go to your browser and visit:
https://yourwebsite.com/wp-json/
You should see a JSON response with available API routes. For example:

{
  "name": "My Headless Site",
  "description": "Just another WordPress site",
  "url": "https://yourwebsite.com",
  "namespaces": ["wp/v2"]
}

Fetch Posts via API

Try accessing your posts:
https://yourwebsite.com/wp-json/wp/v2/posts
This returns a JSON list of your blog posts, including titles, content, and featured images.

Test with Postman or Browser

Use tools like Postman or simply your browser to test API endpoints. This helps confirm your content is accessible before building the front end.

Step 3: Choose a Front-End Framework

Now it’s time to build the user-facing side of your site. You’ll connect it to your WordPress backend using the REST API.

Popular Options

  • React: A flexible JavaScript library for building interactive UIs.
  • Next.js: A React framework with server-side rendering and static site generation—great for SEO.
  • Gatsby: A static site generator that pulls data from WordPress at build time.
  • Nuxt.js: The Vue.js equivalent of Next.js.

For beginners, Next.js is a strong choice because it handles routing, SEO, and performance out of the box.

Step 4: Build the Front-End Application

Let’s walk through creating a simple blog front end using Next.js.

Set Up Next.js

Open your terminal and run:

npx create-next-app@latest my-headless-site
cd my-headless-site
npm run dev

This creates a new Next.js app and starts a local server at http://localhost:3000.

Fetch Posts from WordPress

Create a new file at pages/index.js and add this code to fetch and display posts:

export async function getStaticProps() {
  const res = await fetch('https://yourwebsite.com/wp-json/wp/v2/posts');
  const posts = await res.json();

  return {
    props: { posts },
    revalidate: 10, // Regenerate page every 10 seconds
  };
}

export default function Home({ posts }) {
  return (
    <div>
      <h1>My Headless Blog</h1>
      {posts.map(post => (
        <article key={post.id}>
          <h2>{post.title.rendered}</h2>
          <div dangerouslySetInnerHTML={{ __html: post.content.rendered }} />
        </article>
      ))}
    </div>
  );
}

Style Your Site

Add CSS using Next.js’s built-in support. Create a styles/globals.css file and import it in _app.js. You can also use Tailwind CSS or styled-components for more advanced styling.

Step 5: Deploy Your Headless Site

Once your front end is ready, deploy it to a hosting platform.

Deploy Next.js

Vercel (created by the makers of Next.js) offers seamless deployment:

  • Push your code to a GitHub repository.
  • Connect it to Vercel.
  • Vercel automatically builds and deploys your site.

Deploy WordPress

Your WordPress backend should remain on a secure hosting provider. Avoid exposing it to the public unnecessarily. Use a subdomain like cms.yourwebsite.com for the admin area.

Troubleshooting Common Issues

Here are some common problems and how to fix them:

CORS Errors

If your front end can’t access the API due to CORS (Cross-Origin Resource Sharing) issues, install the WP CORS plugin or add this to your functions.php:

add_action('rest_api_init', function () {
  remove_filter('rest_pre_serve_request', 'rest_send_cors_headers');
  add_filter('rest_pre_serve_request', function ($value) {
    header('Access-Control-Allow-Origin: *');
    header('Access-Control-Allow-Methods: GET');
    return $value;
  });
});

API Returns 404

Ensure permalinks are set to “Post name” in Settings > Permalinks. This enables clean URLs required for the REST API.

Images Not Loading

Featured images are returned as IDs. Use the _embed parameter in your API request:
https://yourwebsite.com/wp-json/wp/v2/posts?_embed
This includes image URLs in the response.

Conclusion

Creating a headless WordPress site unlocks powerful possibilities. You keep the ease of WordPress content management while gaining the speed and flexibility of modern front-end tools. Whether you’re building a blog, portfolio, or enterprise app, this architecture scales beautifully.

Start small—build a simple blog with Next.js and your WordPress backend. As you grow, explore advanced features like authentication, dynamic routing, and incremental static regeneration. With headless WordPress, the only limit is your imagination.
