How to use webRequestFilter and webResponseFilter in WooCommerce.NET

1. In you project, define filter functions:

        private void RequestFilter(HttpWebRequest request)
        {
            request.UserAgent = "custom-user-agent";
        }

        private void ResponseFilter(HttpWebResponse response)
        {
            var total = int.Parse(response.Headers["X-WP-Total"]);
            var pagecount = int.Parse(response.Headers["X-WP-TotalPages"]);
        }

var api = new RestAPI("http://www.yourstore.co.nz/wp-json/wc/v2/", "<WooCommerce Key>", "<WooCommerce Secret>", requestFilter: RequestFilter, responseFilter: ResponseFilter);
