Modify WooCommerce REST API Product Response

woo-product-api-filter.php

<?php
// add this code to a custom plugin
add_filter( 'woocommerce_rest_prepare_product_object', 'wc_app_add_custom_data_to_product', 10, 3 );

// filter the product response here
function wc_app_add_custom_data_to_product( $response, $post, $request ) {
  // in this case we want to display the short description, so we copy it over to the description, which shows up in the app
  $response->data['description'] = $response->data['short_description'];
  return $response;

}

@naumanahmed19 it looks like the correct filter now includes object woocommerce_rest_prepare_product_object http://hookr.io/actions/woocommerce_rest_prepare_product_object/
