We are currently in development for a couple apps that allow someone to post in the companies Fan Page, so we need the manage_page and publish permissions, which require approval, in this case the apps will NOT be made public (only 1 person will use it at all times), so my question is, can i keep using it in development mode or do i need to still go through the approval process?
After asking in the Facebook Group the consensus is, use your app on development mode. Thought i'd post this in case someone else is wondering this.
