  How did theREST API come about? • Proposed just after the WP Community Summit in 2012 • JSON over XML because of how it maps to programming language constructs • REST because the REST paradigm matches up well with the CMS structure • Merged* into Core on October 8, 2015

  Is the WPREST API part of WP Core? • Yes* • Infrastructure is in core • Prebuilt endpoints aren’t in core • We can create our own endpoints without an additional plugin • If we want all the endpoints we need a plugin
• 10.
  What does theplugin give us? • Endpoints on posts, pages, revisions, media, post types, post statuses, comments, taxonomies, categories, tags and users • Can be enabled for CPT or custom taxonomy • For a full list, see the reference
• 11.
  And without theplugin? • No endpoints available, but they can be created • Step 1: Create a function to return the necessary data • Step 2: Register with register_rest_route • Step 3: Flush Rewrite Rules • Step 4: Profit!
