Wordpress REST API 404 error when requesting Custom Post Type with Mobile Browser

Question

I am confused. I am using Wordpress REST Api to build a mobile app with Ionic. I am trying to implement regular post type and one of my custom post type.

I can make a get request for the standard post type "http://www.example.org/wp-json/wp/v2/posts" and it works.

I did the same with my custom post type "http://www.example.org/wp-json/wp/v2/shows" and when I test it in my browser it works BUT when I use chrome and the mobile simulator it gives me an 404 error : rest_no_route

Any ideas why this error occurs, especially only for custom post types?

By default custom post type won't be available. You need to add the below snippets to functions.php of your theme file:

add_action( 'init', 'custom_post_type_rest_support', 25 );
function custom_post_type_rest_support() {
  global $wp_post_types;

  $post_type_name = 'show';
  if( isset( $wp_post_types[ $post_type_name ] ) ) {
    $wp_post_types[$post_type_name]->show_in_rest = true;
    $wp_post_types[$post_type_name]->rest_base =  $post_type_name ;
    $wp_post_types[$post_type_name]->rest_controller_class = 'WP_REST_Posts_Controller';
  }
}
