Unable to retrieve post impressions with Facebook FQL
I'm trying to query FB for a Page Stream using FQL in PHP, and I get all the data except impressions. The FB_ACCESS_TOKEN used is the OAuth token for my FB App, where I have granted the following scope: offline_access,manage_pages,email,read_insights,sms,publish_stream
Code example:
$this->fb->api(array(
"method" => "fql.multiquery",
"queries" => json_encode(array(
"post" => "SELECT post_id, source_id, updated_time, created_time, actor_id,
message, attachment, impressions, likes, privacy,
permalink, comments
FROM stream WHERE source_id='".$source_id."'
AND created_time > '".$date_updated."'",
"comment" => "SELECT post_id, fromid, time, text, id, likes, object_id
FROM comment WHERE post_id IN (SELECT post_id FROM #post)
AND time> '".$date_updated."'"
)), access_token" => FB_ACCESS_TOKEN
));
Here is the example output:
[...]
[0] => Array(
[post_id] => 107112482661088_236459409726394
[source_id] => 107112482661088
[updated_time] => 1312884237
[created_time] => 1312884237
[actor_id] => 608795063

[friends] => Array()

[comments] => Array(

[comment_list] => Array()
)
)
[...]
Any suggestions or reasons why I don't get the impression data?
Have you tried this query for a post that is several days old?
Facebook Insights seems to usually be 24 to 48 hours behind and I believe that is the source of the impressions value.
To validate, I ran your FQL query for a post created today on a page that I have read_insights permissions for. The result for "impressions" was null (like in your example).
I then ran the same query for a post three days ago and the number of impressions was present.
