When you use OmniAuth to login to a web app through Facebook, these are the permissions the webapp has:

Access my basic information Includes name, profile picture, gender, networks, user ID, list of friends, and any other information I've shared with everyone.

Send me email WebApp may email me directly at email@email.com

Access my data any time WebApp may access my data when I'm not using the application

Whereas when you use the mini_fb gem to link a web app to Facebook, these are the permissions (have to specify this as code otherwise formatting was weird):

I’m using OmniAuth at the moment, and would like to keep doing so, but my app needs more permissions, like some of the extra ones that mini_fb has. Does anyone know how I can customize OmniAuth to request extra permissions?

    You can check on option using the :scope attribute:

    use OmniAuth::Strategies::Facebook, 'app_id', 'app_secret', {:scope => 'email,offline_access, your,scope,you,want'}

    Check the Facebook permissions documentation what scope you really want and define it separate by a commant on :scope option.

    If you use an initializer to define your OamniOauth, it’s like that:

    Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, 'APP_ID', 'APP_SECRET', {:scope => 'email,offline_access, your,scope,you,want'}
end
