I am using C # to search for orders from last month (last 30 days). Magento version 2 using REST, I am using the call as follows:

http://magentoserver/index.php/rest/V1/orders?searchCriteria[filter_groups][0][filters][0][field]=created_at&searchCriteria[filter_groups][0][filters][0][value]=2017-08-01&searchCriteria[filter_groups][0][filters][0][condition_type]=gt

The remote server returned an error: (401) Unauthorized.

If the call is:

http://magentoserver/index.php/rest/V1/orders?searchCriteria=

The server returns all orders.

It's not an authorization error, I really don't find the right way to build the search criteria. I don't find any documentation that explains how to do it

I'm building the code like this:

    public class ApiClient

{



    public ApiClient(string magentoServer, string consumerKey, string consumerSecret, string accessToken, string accessTokenSeccret)

    {

        MagentoServer = magentoServer;

        ConsumerKey = consumerKey;

        ConsumerSecret = consumerSecret;

        AccessToken = accessToken;

        AccessTokenSecret = accessTokenSeccret;

    }



    #region Request



    public HttpWebRequest CreateAuthorizedRequest(string url, string requestMethod, string filter)

    {

        HttpWebRequest request = null;

        if (filter == null)

            request = (HttpWebRequest)WebRequest.Create(url);

        else

            request = (HttpWebRequest)WebRequest.Create(url + "?" + filter.ToString());



        OAuthBase oAuth = new OAuthBase();

        string nonce = oAuth.GenerateNonce();

        string timeStamp = oAuth.GenerateTimeStamp();

        string parameters;

        string normalizedUrl;

        string signature = oAuth.GenerateSignature(new Uri(url), ConsumerKey, ConsumerSecret,

        AccessToken, AccessTokenSecret, requestMethod, timeStamp, nonce, OAuthBase.SignatureTypes.HMACSHA1,

        out normalizedUrl, out parameters);



        StringBuilder sb = new StringBuilder("OAuth ");

        sb.AppendFormat("oauth_token="{0}",", AccessToken);

        sb.AppendFormat("oauth_version="{0}",", "1.0");

        sb.AppendFormat("oauth_signature_method="{0}",", "HMAC-SHA1");

        sb.AppendFormat("oauth_nonce="{0}",", nonce);

        sb.AppendFormat("oauth_timestamp="{0}",", timeStamp);

        sb.AppendFormat("oauth_consumer_key="{0}",", ConsumerKey);

        sb.AppendFormat("oauth_signature="{0}"", signature);



        request.Headers[HttpRequestHeader.Authorization] = sb.ToString();

        request.Method = requestMethod;



        request.Accept = "application/json";

        request.ContentType = "application/json";

        request.KeepAlive = true;



        return request;

    }



    public string FetchRequest(HttpWebRequest request)

    {

        try

        {

            string responseText = string.Empty;

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            if (response.StatusCode == HttpStatusCode.OK)

            {

                using (Stream responseStream = response.GetResponseStream())

                {

                    using (StreamReader responseReader = new StreamReader(responseStream))

                    {

                        responseText = responseReader.ReadToEnd();

                        return responseText;

                    }

                }

            }



            return responseText;

        }

        catch (WebException ex)

        {

            Console.WriteLine("Error: " + ex.Message);

            return null;

        }

    }













    public static string GetValues(string _call, string method)

    {

        ApiClient client = new ApiClient(MagentoServer, ConsumerKey, ConsumerSecret, AccessToken, AccessTokenSecret);

        string url = url_base + _call;

        string t = null;

        HttpWebRequest myReq = client.CreateAuthorizedRequest(url, method, null);

        t = client.FetchRequest(myReq);

        if (t != null)

            t = t.Replace("\/", "/");

        return t;

    }

The call it's made like:

        public string url = "http://" + magentoServer;

        public string url_base = "/index.php/rest/V1/";





        string _call = "orders?";

        _call += "searchCriteria[currentPage]=1&";

        _call += "searchCriteria[pageSize]=1";

        string _resp = Magento2Form.GetValues(_call, "GET", null);

This single call only with pageSize and currentPage gives me the answer:

Error: The remote server returned an error: (401) Unauthorized.
