Rest API response not translated.

Hi,

This is still an issue for me. I have tried it on a new installation and putting /de/ before wp-json doesn’t seem to do anything.

This is the solution I wrote for now, but this only includes the product name.

function rijcew__add_translated_name_to_woo($response, $post, $request)
{
    if (get_locale() == 'DE_de_formal') {
        $original_string = $response->data['name'];

        // Global WordPress database access class
        global $wpdb;

        // Table name with correct prefix
        $table_name = $wpdb->prefix . 'trp_dictionary_en_us_de_de_formal';

        // Prepare and execute SQL query to retrieve the translation
        $query = $wpdb->prepare(
            "SELECT translated
        FROM $table_name
        WHERE original = %s",
            $original_string
        );

        $translated_string = $wpdb->get_var($query);

        if ($translated_string !== null) {
            $response->data['name'] = $translated_string;
        }
    }

    $response->data['name'] = $response->data['name'];
    return $response;
}
add_filter('woocommerce_rest_prepare_product_object', 'rijcew__add_translated_name_to_woo', 10, 3);

Could you help me further with this issue? I also need the description & slug translated as I expect it.
