WooCommerce REST API: Random sorting for products and other post types.

readme.md

Usage example

Endpoint: {your_website}/wp-json/wc/v3/products?orderby=rand

functions.php

<?php // functions.php

/**
 * rest_{post_type}_collection_params
 *
 * @param array $params
 * @return array
 */
add_filter( 'rest_product_collection_params', function ( $params ) {
  $params['orderby']['enum'][] = 'rand';
  return $params;
});

Thank you. This helps me a lot.

However, I have a question.
How to change the default orderby to rand ?

@sarimoon98

add_action('pre_get_posts' function($query) {
    if ($query->is_main_query() && ! is_admin()) {
        $query->set("orderby", "rand");
    }
});
