This seems like a silly question, but I can't figure out how to find exactly what permissions my facebook app asks users for. Ideally, there should be a list somewhere that I can add to/delete from/edit.
When I go to Apps > my_app > Permissions, I get a "Configure your permissions" box, but it does not list what permission my app currently asks for.
Adding the permissions in the App Settings is for the App Centre only.
The permissions will actually be asked in the app only if you add them in your login code.
For eg, if you are using-
PHP SDK
$params = array(
'scope' => 'perm1','perm2'..
);
$loginUrl = $facebook->getLoginUrl($params);
Javascript SDK
FB.login(function(response) {
// handle the response
}, {scope: 'perm1, perm2'});
