For an interactive kiosk project I need to add the functionality for the user to “Ask to join” a certain group.
I was imagining this would be pretty straight forward, but I can’t really find any trace of this functionality in the Graph API…
Does this functionality exist at all?
Unfortunately as far as I know you can’t programatically make a user join a group (due to security and privacy issues), same goes with liking a page (you have to ask a user to do that manually).
However what I can suggest doing is checking if a given user is already a member of that group (using the group_member table) and if not, redirecting him to the group and asking him to join it.
