  +| ConsumerKey | The consumer key that is required with all calls to the Xero API., | True |
  +| ConsumerSecret | The secret key from the developer portal that is required to authenticate your API calls | True |
  +| AuthorizeCallbackUrl | The callback that Xero should invoke when the authorization is successful. | False |

  **Note:** `RunscopeBucketId` has been added to support debugging the SDK. Runscope is a simple tool for Testing Complex APIs. You can use Runscope to verify that the structure and content of your API calls meets your expectations.
  Sign up for a free runscope account at http://runscope.com and place your bucket ID in the config file to monitor API calls in real time.
