title: InvalidTokenException: Unauthorized-401
body: <p>I am converting a application to use IPP .net API V3. I have already built all the OAuth and saved the token info.  Trying to make connection but always get error.  I have checked and recheck all the token data and it appears correct.  Where did I go wrong? I am using the DevDefined for OAuth and Intuit.Ipp from NuGet (IPP API V3). I am using my test customer token info but noticed the base URL (from the IPP library) is <a href="https://quickbooks.api.intuit.com/" rel="nofollow">https://quickbooks.api.intuit.com/</a>.  Should that still work? </p>
  
  <pre><code>        Dim accessToken As String = QBOE.GetOAuthItem(Profile.Common.StoreNum, "accessToken")
      Dim accessTokenSecret As String = QBOE.GetOAuthItem(Profile.Common.StoreNum, "accessTokenSecret")
      Dim consumerKey As String = ConfigurationManager.AppSettings("consumerKey")
      Dim consumerSecret As String = ConfigurationManager.AppSettings("consumerSecret")
      Dim oauthValidator As OAuthRequestValidator = New OAuthRequestValidator(accessToken, accessTokenSecret, consumerKey, consumerSecret)
  
      Dim CompanyID As String = QBOE.GetOAuthItem(Profile.Common.StoreNum, "CompanyID")
      Dim appToken As String = ConfigurationManager.AppSettings("applicationToken")
      Dim context As ServiceContext = New ServiceContext(appToken, CompanyID, IntuitServicesType.QBO, oauthValidator)
  
      Dim service As DataService = New DataService(context)
  
      Dim customer As Customer = New Customer()
      'Mandatory Fields
      customer.GivenName = "Mary"
      customer.Title = "Ms."
      customer.MiddleName = "Jayne"
      customer.FamilyName = "Cooper"
  
      Dim resultCustomer As Customer = TryCast(service.Add(customer), Customer)

  <p>I checked the calls within fiddler2 and noticed the calls for my OAuth is going through workplace.intuit.com:443 but the IPP calls go through quickbooks.api.intuit.com:443. I also noticed fiddler2 list the IPP call with a Result of 200.  Output shown below.</p>
