My question is following.
I am trying to follow "Integration Workbook" from SalesForce, and I have problems with OAuth.
It seems I am missing something important but I can't understand what it is exactly.
So, when I try to access external java heroku callout application http://bdovhan-sfjavaco-advanced.herokuapp.com/orderui I see error
"redirect_uri must match configuration"
despite I have been steps from Integration Workbook.
which I have copied to heroku.
So, what is wrong?
