I’m just getting started with the Facebook Graph API and I’m getting the impression that the API is more restrictive than the website in what information it will provide me.
Experimenting with the Graph API Explorer I seem to be unable to list friends of friends for instance. Is this to be expected? Is the set of information that I can get out via the Facebook Graph API just a subset of the data I can get out via the Facebook web interface?
Yes, of course it is.
Naturally. If you could get not only friends of the active user, but friends of friends also – nothing would stop an app from “mapping” the whole graph of who’s friends with whom by repeating this step over and over again.
Definitively.
