[wp-hackers] Building a JSON API style plugin

[Adriaan Pelzer]

I usually implement a simple json api as one or more custom post types.

There are many different approaches to this. You can implement an entire
API in a single post type (and its corresponding php template) using $_GET,
$_POST, etc parameters, or you can organise it a bit more.

In a nutshell:

   1. Create a custom post type per call
   2. Create a post per resource (keep in mind its easy to automate this)
   3. Implement the JSON output in the single-<postslug>.php template file
   4. You can use the archive-<postslug>.php file for overview or "listing"
   calls

Example:

   1. custom post type: tickets
   2. Archive - returns list of tickets
   3. Single - returns details of a single ticket

You get the idea ...
