Facebook insights, page_fans_country accessible, no data for page_fans, page_fans_locale or page_fans_gender_age -
i'm using fql access pages insights , i've got different results depending on metric pass in query.
for exemple, query works correctly, datas facebook pages :
select value insights object_id='pageid' , metric='page_fans_country' , end_time=end_time_date('2013-04-14t07:00:00+0000') , period='0'
but if use metric page_fans_gender_age or page_fans_locale, don't data, except 1 specific page (which maybe related token).
i don't understand why metric working differently, don't see specific infos in graph documentation ?
are page_fans_country insights datas "public" not other metrics ?
can token problem ? or depend on end_time parameters ?
is problem related bug : https://developers.facebook.com/bugs/345809555540652?browse=search_5148c3f9aa0392220388804
yes - page_fans_country
publicly available, other metrics require appropriately authenticated token. it's worth, don't think 0
valid period, either.
normally can avoid end_time
issues selecting date few days in past (insights has variable lag time, around 3 days).
