问题
I have a Facebook app which has Facebook login as a product. My requirement is to fetch the comments on my posts in group/page and view the email and name of the user who has commented.
I'm using graph API to fetch the comment from a post with
{post-id}/comments
Further more I can fetch the user from each comment by
{comment-id}?fields=from
although this works when a user has given permission to my app. I'm unable to get the email of the user from the above endpoint.
Also how can I mandate that the users in my Group/Page must give permissions to my app if I'm a group admin/page admin.
