Lists: Custom Post Types and Post Meta
The WP-API doesn't support custom post types or post meta by default. Adding them is just a few lines of code, we have a sample plugin file to help.
You will need to edit this file, all of the functions are commented out by default. Please read through the code, make any changes necessary, then add it to your site as a plugin.
For more information on adding custom data to lists using template hooks, see this article.
