Difference between 'Page tab' and 'Application on Facebook'
Solution
Er, one is an app to be installed as tab on a Facebook page and the other isn a canvas app accessed at apps.facebook.com/appname - The documentation covers the two types of app pretty clearly:
Canvas apps: https://developers.facebook.com/docs/guides/canvas/
Page tab apps: https://developers.facebook.com/docs/appsonfacebook/pagetabs/
Problem
I would like to know what is the difference between those two categories that I have to select when I register the 'application' (this term applies also for the 'Page tab'). Thanks
