Using the PHP SDK, i'm trying to get post_impressions for specific posts. I've set a valid default access token using setDefaultAccessToken(), and then im trying:
$request = $fb>get("/$post_id/insights/post_impressions");
$graphEdge = $request->getGraphEdge();
var_dump($graphEdge);
I've also tried to prepend $page_id followed by underscore to the $post_id in the request, as explained here, but no luck.
The response i get from the request above is an object with protected properties with my app_id, secret_id, my request method.
No data about the post though.
Any ideas on what im missing out here?
