How do I get the session_key for a permanent "offline_access" permission?

Question

Hi all,

I writing a server-side backend for a mobile app that will allow posting media to facebook.

I need to post images to the user's profile.

I get the user to add the application + the user allows me to "offline_access"

From Facebook documentation I see that I need to pass the "session_key" on every api request I am doing (using the restful API).

I've forwarded the user to prompt_permissions.php but when he allows the offline_access - I don't get any signature/key ...

What am i DOING WRONG?

Answer 1

look for the cookie labeled:

$APIKEY_session_key

where $APIKEY is your API key.

this cookie contains the offline session key that you can use.
