is it possible to get the friend lists from an user with the APP secret(not with the access token) by using the open graph?
The User has already installed the APP.
Thanks in advance.
PS:
If I understand aright …
-> graph API = only works with the acces token
-> FQL = works with access token and app secret
Right?
I´ve never heard that you can use an app secret with FQL. Theoretically it is impossible to get the friend list from a user with the app secret only, because the app secret is the same for all users. There are only different access tokens (page token, app token, user token), but to get the friends of a user you will always need a user access token.
Btw, you don´t really need to worry about that if you are using one of those SDKs (PHP SDK, JS SDK…).
Also, it is best practice to use the Graph API if there is a possibility, and FQL only if there is non (good) way with the Graph API.
