In the following snippet, you can register a new endpoint in the API to access random posts.
This can be configuring to work with any post-type. You’ll just updating the get_posts array accordingly. Enjoy!
You’ll want to put this inside your functions.php inside your Theme, or create a plugin. If you’re extending the WordPress REST API further you should probably just create a plugin.
add_action( 'rest_api_init', function () { register_rest_route( 'api', '/any', array( 'methods' => 'GET', 'callback' => 'get_random', ) ); }); function get_random() { return get_posts( array( 'orderby' => 'rand', 'posts_per_page' => 3) ); }
