Download Quickbooks IPP.NET SDK it will provide you different classes for CURD.
var appToken = "";
var consumerKey = "";
var consumerSecret = "";
// the above 3 fields you can get when create your app on quickbook go to My app----> select youre app--->goto KEYS
var accessToken = "";
var accessTokenSecret = "";
// this two tookens you will get from URL on the same above page
var realmId = "1400728630"; //1400728630
// this is youre company ID which can be used when you create youre //company on freshbook
var serviceType = IntuitServicesType.QBO;
var validator = new OAuthRequestValidator(accessToken, accessTokenSecret, consumerKey, consumerSecret);
var context = new ServiceContext(appToken,realmId, serviceType, validator);
var service = new DataService(context);
try
{
Customer customer = new Customer();
//Mandatory Fields
customer.GivenName = "Mary";
customer.Title = "Ms.";
customer.MiddleName = "Jayne";
customer.FamilyName = "Cooper";
service.AddAsync(customer);
//service.Add(entity);
}catch(Exception ex)

System.Console.WriteLine(ex);
