I am just starting to develop a first Box (administrative) app, and would like to obtain a first authorization code for an admin user. When I use 'http://localhost' as the redirect url in the app's configuration, I see that when the admin user 'grants' access to the app, the (Chrome) browser shows the following address in the url after clicking on 'grant':
'localhost/blah' (sort of as expected) but however, it displays a blank page, and my Java app installed at 'http://somehostname:80/blah' does not get called (this is what I was expecting would happen).
Am I misunderstanding what should be happening when using a 'localhost' redirect uri?
Any help will be appreciated. Thanks!
