18. Merge meline WordPress 4.4 (8 December 2015) Infrastructure merged No endpoints WordPress 4.7 (due 6 December 2016) Endpoints merged!
19. 2. How the WordPress REST API works (aka, what the heck is an endpoint?)
20. End‐what? REST APIs interprets a URL, and return a response Not wildly different to RSS Sample request to fetch some posts: wc-athens.dev/wp-json/wp/v2/posts
21. [ { "id": 1, "date": "2016-11-18T14:08:53", "date_gmt": "2016-11-18T14:08:53", "modified": "2016-11-18T14:08:53", "modified_gmt": "2016-11-18T14:08:53", "slug": "hello-world", "type": "post", "link": "http://wp-rest-api-demo.dev/2016/11/18/hello-wor "title": { "rendered": "Hello world!" }, "content": { "rendered": "<p>Welcome to WordPress. This is your fi "protected": false } } ]
22. More endpoints... Single post: wc-athens.dev/wp-json/wp/v2/posts/1 All pages: wc-athens.dev/wp-json/wp/v2/pages All users: wc-athens.dev/wp-json/wp/v2/users All categories: wc-athens.dev/wp-json/wp/v2/categories
