If I have the url of the group ex https://www.facebook.com/groups/angularjs.dev/ How to I get the group Id of it.
If I have a facebook page(https://www.facebook.com/raspberrypi/) I'm able to get the ID from https://graph.facebook.com/v2.8/https://www.facebook.com/raspberrypi/.
But this is not working for facebook Groups.
