I am trying to get the user id of those that 'likes' and 'react' to a posts(post not belonging to me). I notice that from the graph api explorer, likes and reactions are greyed out. Any advise if I can get those details?
Thanks. Jeff

/page/* — User information will not be included in GET responses for any objects owned by (on) a Page unless the request is made with a Page access token. This affects all nodes and edges that return data for objects owned by a Page.
In other words: If you don´t own the Page where the Post belongs to, it´s impossible to get user data.
