title: Error while calling google+ method plusService.People.Get
body: <p>The Google+ API is set to "On" from google's developer console. I am fetching the profile information of the user by supplying the api key but I get an error saying:</p>
  
  <p>Access Not Configured. Please use Google Developers Console to activate the API for your project. [403]</p>
  
  <pre><code>  BaseClientService.Initializer ini = new BaseClientService.Initializer { ApiKey = "" };
    PlusService plusService = new PlusService(ini);
    if (plusService != null)
    {
           PeopleResource.GetRequest prgr = plusService.People.Get("me");
           Person googleUser = prgr.Execute();
    }
  </code></pre>
  
  <p>The error is thrown when Execute is called.</p>
  
  <p>Does this service needs to be set up with "billed" profile ? This may be the reason I am getting access error.</p>
