Хотя, кажется, существует множество ответов, ни один из них, похоже, не работает для меня. Мне нужно интегрировать wordpress с сайтом woocommerce и использовать OAuth 1.0.

У меня есть следующая база кода, но я продолжаю получать ошибку недопустимой подписи.

 private static readonly RNGCryptoServiceProvider random = new RNGCryptoServiceProvider();

public RestClient() {
    site = ConfigurationManager.AppSettings["ukstore"];
    consumerkey = ConfigurationManager.AppSettings["wookey"];
    woosecret = ConfigurationManager.AppSettings["woosecret"];
}

public async Task<string> PostToWoo<T>(string endpoint, T postdata)
            where T : class {
    var request = new RestRequest(Method.POST);

    var fullEndPoint = string.Concat(site, "/wp-json/wc/v3/", endpoint);

    var serializedData = JsonConvert.SerializeObject(postdata);
    var restpoint = BuildAuthorisationUrl(fullEndPoint);

    var client = new RestSharp.RestClient(restpoint);
    client.Timeout = -1;
                
    request.AddHeader("Content-Type", "application/json");

    request.AddJsonBody(serializedData);
    var response = await Task.Run(() => client.Execute(request));

}

private string BuildAuthorisationUrl(string Url)
{
    var sb = new StringBuilder();
    var nonce = GenerateNonce(11); 
    var timeStamp = Math.Truncate((DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0)).TotalSeconds).ToString(); 
    var signature = GenerateSignature(nonce, timeStamp, new Uri(Url));

    sb.Append(GenerateQueryStringOperator(sb.ToString())   "oauth_consumer_key="   Uri.EscapeDataString(consumerkey));
    sb.Append("amp;oauth_signature_method="   Uri.EscapeDataString("HMAC-SHA1"));
    sb.Append("amp;oauth_timestamp="   Uri.EscapeDataString(timeStamp));

        {"oauth_nonce", nonce},
        {"oauth_version", "1.0"}
    };

    var sb = new StringBuilder();
    sb.Append(Uri.EscapeDataString(url.AbsoluteUri));
    sb.Append("amp;"   Uri.EscapeDataString(NormalizeParameters(parameters)));
    return sb.ToString();
}

private string GenerateQueryStringOperator(string currentUrl)
{
    if (currentUrl.Contains("?"))
        return "amp;";
    else

    var i = 0;
