Can somebody post a bit of example code for locales and countries?
There is really nothing in the api and the net overall although this feature is so powerful!
Code example that worked for me:
curl -F 'access_token=[page_access_token]'
-F 'message=Testing post to certain language'
-F 'link=http://stackoverflow.com/questions/15280604/can-you-gate-and-target-a-page-post-through-the-facebook-graph-api'
-F 'feed_targeting={'locales':[1001]}'
https://graph.facebook.com/[pageID]/feed
To get language numbers:
curl -G -d "access_token=xx" -d"q=en"
-d "type=adlocale"
https://graph.facebook.com/search
A bit of help is the Targeting from the ads api doc but only some fields are possible for post targeting.
To get locales,city,... codes graph search via curl
Hope this helps someone!
