This updated tutorial demonstrates how to retrieve a list of WordPress posts using the WordPress REST API and Postman. The tutorial has been refreshed with current examples and information.

This article was updated in mid-2025 with current information and examples.

This example showcases how to fetch a list of posts from a modern WordPress installation using the REST API. For optimal interaction, Postman is recommended.

WordPress, an open-source Content Management System (CMS) launched in 2003 (a fork of b2/cafelog from 2001), powers over 26% of the global web (according to WPManage) and holds approximately a 60% market share, making it the most popular CMS. Recent WordPress versions include a built-in REST API, opening up numerous possibilities. Developers can now build applications that interact remotely with WordPress sites, exchanging data via JSON. This eliminates the reliance on PHP, allowing the use of any language capable of handling JSON.

Download Postman here:

After launching Postman, enter this URL:

<code>https://www.sitepoint.com/wp-json/wp/v2/posts?per_page=3</code>

Ensure "GET" is selected and click "Send." A JSON response will be returned. A partial example is shown below:

<code>[
  {
      "id": 157538,
      "date": "2017-07-21T10:30:34",
      "date_gmt": "2017-07-21T17:30:34",
      "guid": {
          "rendered": "https://www.sitepoint.com/?p=157538"
      },
      "modified": "2017-07-23T21:56:35",
      "modified_gmt": "2017-07-24T04:56:35",

      },
      "content": {

      },
      "excerpt": {
          ...
      },
      "author": 72546,
      "featured_media": 157542,
      "comment_status": "open",

      "tags": [

      ],

      }

Frequently Asked Questions (FAQs) about the WordPress JSON REST API:

Q: What is the WordPress JSON REST API?

A: The WordPress JSON REST API is a standardized interface for interacting with WordPress sites using HTTP requests and JSON. It allows for creating, reading, updating, and deleting data.

Q: How do I use it?

A: Send HTTP requests to specific endpoints (URLs) for different resources (posts, pages, etc.). The request type (GET, POST, PUT, DELETE) determines the action. Tools like Postman or cURL can be used.

Q: What are its benefits?

A: Language-agnostic interaction, standardized data access, creation of more dynamic user experiences.

Q: How do I authenticate?

A: Cookie authentication (for plugins/themes on the same site), OAuth 1.0a, or basic authentication (username/password, often requiring plugins).

Q: Can I customize it?

A: Yes, using WordPress hooks and filters.

Q: What is the JSON Content Importer plugin?

A: A WordPress plugin for importing and displaying data from any JSON feed, including the WordPress REST API.

Q: How do I install it?

A: Through the WordPress plugin dashboard.

Q: How do I use the JSON Content Importer plugin?

A: Use its shortcode within posts or pages, specifying the JSON feed URL and display options.

Q: What's the difference between the API and the plugin?

A: The API allows direct interaction, while the plugin imports and displays data from any JSON source.

Q: Can I use the API for mobile apps?

A: Yes, to fetch and manage data for your app.
