I have created an app that just wants Users to subscribe for User_events and manage_pages WebHooks subscriptions. As a developer I am able to test the WebHooks at my callback url where I am handling all my graph api calls and retrieving additional information using restfb.
I am confused on having a redirect uri, when I want users to authorize the app. Basically my understanding so far is that I need to make my app public and submit for review in order for others to see. Is redirect uri mandatory for my app? my app wont need users to visit my website or login to any of my callback urls. Only information I need when the user subscribe(or authorize) my app is their uid and pages they are giving me the permission to.
Please note I started reading about facebook webhooks and app development very recently (a week). Any suggestions would be great help.
