We are hiring!@tlovett12
So what’s this new WordPress API thing all about? Don’t we already have
one?
Right now, we have XML-RPC.
Remote Procedural Call API’s are part of an old standard. They are very difficult to use.
Why JSON REST API?
• In a nutshell, JSON REST API’s have swept the web becoming an almost standard. They are extremely intuitive and provide an easy way to distribute, collect, and modify data.
Let’s break it down a bit.
JSON
• JSON is an abbreviation for “JavaScript Object Notation”
• It’s simply a way to describe data that is lightweight and extremely easy to use. Arguably much easier to use than XML.
REST• REST (Representational State Transfer) is an architectural style
that dictates how HTTP and URI’s should be used and organized.
• Verbs and resources: GET /post/1
• Hypermedia as the Engine of Application State (HATEOAS) - Server provides everything you need to know how to use it in a response.
• Actions are autonomous and do not depend on each other.
• Bottom line: RESTful API’s have become extremely popular across the web. They are much easier to use than things like RPC or SOAP.
And of course, API
• An API (Application Programming Interface) is a set of entry points that allow you to interact with a platform (WordPress in this case).
How can I start using it now?
First, install the plugin
http://wordpress.org/plugins/json-rest-api/ !
Core integration coming soon.
What does the API let me to do?
/wp-json/ Shows all the routes and endpoints available
/wp-json/posts Create, read, update, and delete posts
/wp-json/users Create, read, update, and delete users
/wp-json/media Create, read, update, and delete media items
/wp-json/taxonomies Read taxonomies and terms
/wp-json/pages/ Create, read, update, and delete pages
The basic building block of WordPress is the post.http://codex.wordpress.org/Writing_Posts
List Posts
[{! "ID": 11297,! "title": "Post 19",! "status": "publish",! "type": "post",! "author": 1,! "content": "",! "parent": null,! "link": "http:\/\/example.com\/2014\/08\/post-19\/",! "format": "standard",! "slug": "post-19",! "guid": "http:\/\/example.com\/2014\/08\/post-19\/",! "excerpt": null,! "menu_order": 0,! "comment_status": "closed",! "ping_status": "open",! "sticky": false,! "meta": {},! "featured_image": null,! "terms": {}!}]
GET /wp-json/posts
List PostsGET /wp-json/posts

Retrieve A Post
{! "ID": 11297,! "title": "Post 19",! "status": "publish",! "type": "post",! "author": 1,! "content": "",! "parent": null,! "link": "http:\/\/example.com\/2014\/08\/post-19\/",! "format": "standard",! "slug": "post-19",! "guid": "http:\/\/example.com\/2014\/08\/post-19\/",! "excerpt": null,! "menu_order": 0,! "comment_status": "closed",! "ping_status": "open",! "sticky": false,! "meta": {},! "featured_image": null,! "terms": {}!}
GET /wp-json/posts/<id>
Edit A PostPUT /wp-json/posts/<id>
curl -X PUT -H “Content-Type: application/json” -d ‘!{! "title": “Updated Title",! “content_raw": “Updated post content"!}!‘ -u admin:password http://example.com/wp-json/posts/<id>
We need to send a PUT request to this endpoint with our post data. Of course we must authenticate before
doing this.
Create A PostPOST /wp-json/posts/
curl -X POST -H “Content-Type: application/json” -d ‘!{! "title": “Title",! “content_raw": “Post content"!}!‘ -u admin:password http://example.com/wp-json/posts/
Notice we are using a POST request this time.
Build Your Own Routes and Endpoints
WP API is very extensible
