Authorization Issue

[tjstalcup]

Even though we are passing in the clientID: and clientSecret: we are getting this back from the FitBit API:

{ errors: 
   [ { errorType: 'invalid_client',
       message: 'Invalid authorization header format. Visit https://dev.fitbit.com/docs/oauth2 for more information on the Fitbit Web API authorization process.' } ],
  success: false }
