Issues with Accessing Google Docs via GData Integration

I encounter an unauthorized error when using a token-based request for Google Docs in ASP.NET. The modified code sample below demonstrates my new approach. How should I correctly include a token secret?

public ActionResult InitiateAuth()
{
    string redirectUrl = Request.Url.ToString().Replace("initiate", "display").ToLower();
    string scopeUrl = "https://docs.google.com/feeds/";
    string authLink = TokenHelper.GenerateAuthUrl(redirectUrl, scopeUrl, false, true);
    return Redirect(authLink);
}

public ActionResult Display()
{
    if (Request.QueryString["authParam"] != null)
    {
        string tempToken = Request.QueryString["authParam"];
        string keyId = "site.example.com";
        string secretKey = "secret123";
        string sessionKey = TokenHelper.GetSessionToken(tempToken, null).ToString();

        var reqFactory = new AuthRequestFactory("docApp", "app-002")
        {
            Token = sessionKey,
            ConsumerKey = keyId,
            ConsumerSecret = secretKey
        };

        try
        {
            var docService = new DocsService(reqFactory.AppName) { RequestFactory = reqFactory };
            var queryRequest = new DocsQuery() { DocumentTitle = "project" };
            var feed = docService.RunQuery(queryRequest);
            return View(feed.Entries.Select(item => item.Title).ToList());
        }
        catch (ServiceException ex)
        {
            throw ex;
        }
    }
    return null;
}

hey, try combing the token with the secret key per oauth spec. i found that when using the signing helper, it needs both values in a composite key. also check your library’s implementation docs for any overlooked nuances.
