Hi @hauscloud and welcome to the Community! 
Would you mind linking the documentation you were looking at when you set up this application? I’d also like to confirm you’ve added the callback http://hauscloud.me/app/gratitude_journal/callback to your Allowed Callback URLs for your application? Additionally have you looked over this doc on redirecting users after login authentication?
Once I have a better idea of the specific documentation or SDK you’ve referenced I may be able to offer some more guidance and have a better idea of what you’re looking to achieve.
All the best,
Colin
