Facebook Page application tab: when do I get a signed_request and when do I get a fb_sig_page_id? -


i don't know how ask question properly. think title not clear @ all, anyway here's problem.

i'm developing application facebook pages, adds tab page. noticed signed_request string, which, parsed, allows me extract page id, other time bunch of post data, , not signed request... , among data there many variables fb_sig_page_id , other ones.

i don't understand why sometime getting signed_request , other times post data. can me out?

this question asked on fb developer forums adds bit more detail: http://forum.developers.facebook.net/viewtopic.php?pid=316812#p316812

it depends on how facebook application configured. in "advanced" section of facebook configuration of app, "oauth 2.0 canvas" setting. if set true, signed_request. if set false, fb_sig_page_id.

the default changed @ point, older apps have setting set false, , newer apps have set true.
