Modifying responses in woocommerce rest api?

Question

WooCommerce

When rest request /wc/v3/productsthrows out a huge json file with unnecessary fields.

How to make certain fields missing in the response from the server? Through functions.php or maybe something needs to be written in the request itself?

Something like this arrives:


But I want something like this:

Answer 1

in functions.php

add_filter( 'woocommerce_rest_prepare_product_object', 'filter_function_name', 10, 3 );
function filter_function_name( $response, $object, $request ){
    if( empty( $response->data ) )
        return $response;

    $inclde = [
        'id'        => $response->data['id'],
        'name'      => $response->data['name'],
        'images'    => $response->data['images'],
        'price'     => $response->data['price'],
        'meta_data' => $response->data['meta_data'],
        'categories'=> $response->data['categories']
    ];

    return $inclde;
}

WooCommerce has these preparatory filters for most of its API responses. Note that their format is woocommerce_rest_prepare_{$type} where $type is the post type or taxonomy name (e.g. product_cat). In WooCommerce 2.7, some of these filters also have the _object suffix.
You can make rest requests adaptive using the third parameter ($request) in the function and manipulate the response ($response).
Thanks Alex for the tip!

Alternatively, try rest_prepare_{$this->post_type}
