When I submit a get on Graph API Explorer, like that:
me?fields=tagged_places
Works good and return the data of my 'tagged places' to me.
But when I try to get 'tagged places' of my friends, I got this error message:
"error": { "message": "(#100) Unknown fields: tagged_places.", "type": "OAuthException", "code": 100
I want to know if is not possible to get 'tagged_places' of my friends or Im doing something wrong.
You need to have the permission of the item you were tagged in.
