Facebook graph API and Facebook groups -

-

i have 2 questions facebook graphapi , facebook group:

  1. is there way connect existing fb group , new fb app?
  2. i wanna add new member of fb group via fb graph. have code (graph api reference)
$postresult = $this->facebook->api("/group_id/members", "post",        array (         'member' => 'user_id',       )     );

but still error "(#3) unknown method".

the documentation says:

an app access token can invite app users group created app.

so request must made app access token , same app app must have created group.

you cannot send request friends if group not created using app.
