.Net struggles with Webmaster Tools (Google.Apis.Webmasters.v3 Nuget package)

Question

I wonder if anyone has got any further than me using the new Search Analytics functions of the Google Webmaster Tools API via .Net?

I am using the Google.Apis.Webmasters.v3 Nuget package and have got as far as authenticating and connecting (using a Service Account)

However I'm struggling to get anywhere with Search Analytics.

I couldn't find any code samples online so have been guided by the Class info at https://developers.google.com/resources/api-libraries/documentation/webmasters/v3/csharp/latest/annotated.html and a lot of guesswork.

Here is the code I am using:

SearchanalyticsResource mySearchanalyticsResource = new SearchanalyticsResource(service);

SearchAnalyticsQueryRequest myRequest = new SearchAnalyticsQueryRequest(); 
myRequest.StartDate = "2015-08-01"; 
myRequest.EndDate = "2015-08-31"; 
myRequest.RowLimit = 10;

SearchanalyticsResource.QueryRequest myQueryRequest = mySearchanalyticsResource.Query(myRequest, site.SiteUrl); 
SearchAnalyticsQueryResponse myQueryResponse = myQueryRequest.Execute();

It runs OK until the Execute method when I get "An Error occurred, but the error response could not be deserialized". Exception detail below...

Newtonsoft.Json.JsonReaderException {"Error parsing NaN value. Path '', line 0, position 0."}

Any help or code samples would be very gratefully received!

This compiles but its not returning any data for me.

Auth:

 public static WebmastersService WMAuthenticateOauth(string clientId, string clientSecret, string userName)
        {

            string[] scopes = new string[] { WebmastersService.Scope.Webmasters };     // View analytics data

            try
            {
                // here is where we Request the user to give us access, or use the Refresh Token that was previously stored in %AppData%
                UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets { ClientId = clientId, ClientSecret = clientSecret }
                                                                                             , scopes
                                                                                             , userName
                                                                                             , CancellationToken.None
                                                                                             , new FileDataStore(".", true)).Result;

                WebmastersService service = new WebmastersService(new BaseClientService.Initializer()
                {
                    HttpClientInitializer = credential,
                    ApplicationName = "WebMasters API Sample",
                });
                return service;
            }
            catch (Exception ex)
            {

                Console.WriteLine(ex.InnerException);
                return null;

            }

        }

Request

var service = Authentcation.WMAuthenticateOauth(clientid, secret, "testmmm");


   IList<string> newlist = new List<string> ();
   newlist.Add("country");
   newlist.Add("device");

   SearchAnalyticsQueryRequest body = new SearchAnalyticsQueryRequest();
   body.StartDate = "2015-04-01";
   body.EndDate = "2015-05-01";
   body.Dimensions = newlist;

   var result = service.Searchanalytics.Query(body, "http://www.daimto.com/").Execute();

I have also tried testing using the try me at the bottom of this page. It doesn't return anything either.

Strange API this.

Update:

I finally got data back I set the dates to

body.StartDate = "2015-09-01";
body.EndDate = "2015-09-15";

I wonder if this thing has limited data, it only goes back so far.

Thanks so much for your help with this. Sadly, that code results in the same error message as mine at the Execute line: {"Error parsing NaN value. Path '', line 0, position 0."} — Paul Sanders, Sep 16 '15 at 13:37
Ah, that makes sense. Webmaster tools only stores 90 days data. — Paul Sanders, Sep 16 '15 at 13:42
It is very encouraging that you've got data! Unfortunately I am still getting the same error with recent dates. I am using a Service account and keyfile for original authorisation -- I don't know whether that would make any difference. Tried using your code instead, but the OAuth keeps using a different port number so it will never "match a registered redirect URI." — Paul Sanders, Sep 16 '15 at 14:51
Use a native client id not a web one for testing. Service account needs to be granted access somehow I will look at it after dinner — Linda Lawton - DaImTo, Sep 16 '15 at 15:00
Thanks so much. That got round the "doesn't match a registered redirect URI." problem. However, it lead to the same error as I got before. I might try creating a new project from scratch as my code is virtually identical to yours now (except the credentials obvs) but I get this weird error. BTW, you grant the Service account access in Webmaster Tools -- that bit worked for me, just can't get any data :) — Paul Sanders, Sep 16 '15 at 15:13
Would you believe it? I put the same code in a new project and it ran first time. Thanks so much for your help with this. If I didn't know someone else was getting data I would have given up! — Paul Sanders, Sep 16 '15 at 15:35
