Google Analytics Api 400错误请求

Question

I want to import data from Google Analytics.

var gas = new AnalyticsService(auth);

var r = gas.Data.Ga.Get("ga:6332XXXX", "2013-02-01", "2013-02-11", "ga:visits");

r.Dimensions = "ga:date";
r.Sort = "ga:visits";
r.StartIndex = 1;

var data = r.Fetch();

I get 400 bad request error in Fetch method. What is the wrong of my code?

My full code like following:

var scope = AnalyticsService.Scopes.AnalyticsReadonly.ToString();
var clientId = "--------.apps.googleusercontent.com";
var keyFile = @"C:\-----------------privatekey.p12";
var keyPassword = "notasecret";

var desc = GoogleAuthenticationServer.Description;

var key = new X509Certificate2(keyFile, keyPassword, X509KeyStorageFlags.Exportable);

var client = new AssertionFlowClient(desc, key)
{
    ServiceAccountId = clientId,
    Scope = scope
};

var auth = new OAuth2Authenticator<AssertionFlowClient>(client, AssertionFlowClient.GetState);

var gas = new AnalyticsService(auth);

var r = gas.Data.Ga.Get("ga:6332XXXX", "2013-02-01", "2013-02-11", "ga:visits");

r.Dimensions = "ga:date";
r.Sort = "ga:visits";
r.StartIndex = 1;

var data = r.Fetch();

Thaks for your interest.

Answer 1

A couple of ideas:

1. your clientId should be your SERVICE ACCOUNT EMAIL (not id)
2. your scope should be " https://www.googleapis.com/auth/analytics.readonly "
