Apps on Facebook.com. To drive more traffic to apps on Facebook, we enable various channels that enable new users to discover your app as well as existing users to re-engage with your app.
Each channel is designed to help engage users and our algorithms help surface the best content for each user. The current channels include: Newsfeed stories The News Feed is shown immediately to users upon logging into Facebook, making it core to the Facebook experience. Discovery stories. Authentification - Développeurs Facebook. Extended Permissions - Développeurs Facebook. As a general rule, the more permissions an app requests, the less likely it is that people will use Facebook to log into your app.
In fact, our research shows that apps that ask for more than four permissions experience a significant drop off in the number of completed logins. Additionally publishing permissions (publish_actions) will prompt a second step in the Login dialog, which can cause fewer people to log in: Here are a few guidelines to use when asking for permissions, both during and after login: Only ask for the permissions that are essential to an app.Ask for permission in the context in which they are required. For example, if your app wants to show places of interest near a person's home, asking for user_location just prior to displaying that information would give the person a greater understanding of why the permission is being requested.Use any available public profile information before asking for a permission.
