title->rendered – This is the user-readable title of the post.

date – This is the date the post was published on.

We can use this to fetch the post by itself in a future request.

id – This is the ID of the post stored in WordPress.

From the response, we can see WordPress returns a JSON array of post data.

To get a full page of posts, simply hit https:/wp-jon /wp/v2/posts and you should get the latest posts from that WordPress website. Now that we have an understanding, let’s start fetching some posts. Note: When fetching content, unless a website’s API has intentionally been locked down, you should not have to authenticate to make any non-destructive requests. In the case of this example, we are telling WordPress to return posts 100 at a time.

The fifth and final section (pictured in pink) are any additional URL parameters we want to pass to the endpoint action.

For example, the /posts/ endpoint in WordPress tells the site we want to interact with posts.

The fourth section (pictured in blue) is the action in the namespace we want to make.

So, its example path will look like /wp-json/api-bearer-auth/v1/. For example, the plugin API Bearer Auth registers the namespace /api-bearer-auth/v1/. However, third-party plugins can register their own. In our case, /wp/v2/ is the endpoint where all of WordPress’ core endpoints are registered to.

The third section (pictured in red) is the namespace of the endpoint you are working with.

wp-json/ tells WordPress the incoming request is meant for the REST API and not a normal user visiting your website.

The second section (pictured in yellow) is the main path where all WordPress APIs start from.

However, if your WordPress is installed at a directory on the domain, say /blog, your endpoint would be /blog/wp-json/.

The first section (pictured in green) is the domain of where your website is hosted.

Pictured below is what your average endpoint will look like broken into its core parts. Endpoint Primerīefore we explore some example endpoints, it’ll help to understand how the various endpoints are structured. For an exhaustive list of endpoints, a great place to visit is the WordPress Codex over endpoint references. While there are hundreds of endpoints built into WordPress and thousands more that can be added through the use of plugins, we’ll cover some of the most common ones in regards to posts. Just like a city pipe can carry water, sewage, and power to your house, an API can carry data to and from our WordPress site, but unlike a utility company, the other end is yet another website.

Review Common EndpointsĪ good visual I use for understanding the purpose of REST APIs is thinking of them in terms of pipes that connect our code with other websites and servers. One way you can begin working with REST APIs is to use a restful API client-dedicated clients such as Postman (All platforms), Insomnia (All platforms), or my personal favorite Paw (Mac only).Įxample of PAW REST API Client, which you can use with Headless WordPress. This allows you to focus just on the fundamentals of the API instead of the complexities of getting it to work with your existing code. When working with any API system, it is highly recommended to first get familiar with the endpoints you are working with before trying to integrate them into any existing project you are working on.
