Google Admin Directory User Error

Question

Using Google API .NET Client v1.3.0-beta.

I created a console application to test the basics of Google Admin Directory from the sample code for Service Accounts. This should give me a count of all email addresses in the domain.

using System;
using System.Collections.Generic;        
using DotNetOpenAuth.OAuth2;        
using Google.Apis.Admin.directory_v1;
using Google.Apis.Admin.directory_v1.Data;
using System.Security.Cryptography.X509Certificates;
using Google.Apis.Authentication.OAuth2;
using Google.Apis.Authentication.OAuth2.DotNetOpenAuth;
using Google.Apis.Services;
using Google.Apis.Util;

namespace ConsoleApplication1
{
    class Program
    {
        private const string SERVICE_ACCOUNT_EMAIL = "[email protected]";
        private const string SERVICE_ACCOUNT_ID = "012345678901.apps.googleusercontent.com";
        private const string SERVICE_ACCOUNT_PKCS12_FILE_PATH = @"C:\ConsoleApplication1\randomlyassigned-privatekey.p12";    

        static void Main(string[] args)
        {
            X509Certificate2 certificate = new X509Certificate2(SERVICE_ACCOUNT_PKCS12_FILE_PATH, "notasecret", X509KeyStorageFlags.Exportable);
            var provider = new AssertionFlowClient(GoogleAuthenticationServer.Description, certificate)
            {
                ServiceAccountId = SERVICE_ACCOUNT_EMAIL,
                Scope = AdminService.Scopes.AdminDirectoryUser.GetStringValue()
            };

            var auth = new OAuth2Authenticator<AssertionFlowClient>(provider, AssertionFlowClient.GetState);
            var service = new AdminService(new BaseClientService.Initializer()
                {
                    Authenticator = auth
                });

            UsersResource.ListRequest listReq = service.Users.List();
            Users us = listReq.Fetch();
            Console.WriteLine(us.UsersValue.Count);
        }
    }
}

I get the following error when I try to Fetch() the list of users:

Google.Apis.Requests.RequestError
Bad Request [400]
Errors [
    Message[Bad Request] Location[ - ] Reason[badRequest] Domain[global]
]

Any idea what I may be doing wrong here?

Answer 1

I got some help sorting this out. To list users you have to pass domain or customer as an argument for your list-request. Use EITHER CUSTOMER or DOMAIN.

@peleyal helped me findig how to do that:

var listReq = service.Users.List();
listReq.Customer = "CUSTOMER_HERE";
listReq.Domain = "DOMAIN_HERE";
Users results = listReq.Execute(); 

Answer 2

I am also facing the same error [Bad Request] while loading users from domain using new Directory APIs.

To remove errors with the included libraries use the steps mentioned in https://code.google.com/p/google-api-dotnet-client/wiki/Build Also verify that you are using proper version of .Net and not client Profile.
