Facebook API Post Impressions Unique (reach) - facebook

Question

I'm after the impression uniques for our posts and ideally we would like one server call and it would bring back the last 100 posts with the reach (post_impressions_unique).
To get reach, I can currently do this using:
https://graph.facebook.com/nmemagazine/posts?fields=name,message,full_picture,created_time,shares,likes.limit(1).summary(true),comments.limit(1).summary(true)&access_token=USER_TOKEN
and getting the post ID, then calling: https://graph.facebook.com/v2.5/POST_ID/insights/post_impressions_unique?access_token=USER_TOKEN
Is there a way where I can make one call to get all recent posts and their reach in one API call?

Answer 1

You could simply call
https://graph.facebook.com/nmemagazine/posts?fields=name,message,full_picture,created_time,shares,likes.limit(1).summary(true),comments.limit(1).summary(true),insights&access_token=USER_TOKEN
NOTE: extra field "insights".
However, as far as I can tell you cannot limit the insights to just Post_impressions_Unique so it would bring back some data you do not necessarily want/need. I.e. I don't think you can perform a search/filter on a "second level"/child/nested type.

To give an update on this:
In facebook Graph API 2.10, you can (and have to) specify the metrics you are interested in via insights.metric(...). Possible metrics are documented here:
https://developers.facebook.com/docs/graph-api/reference/v2.10/insights#availmetrics
For your example:
curl -i -X GET "https://graph.facebook.com/nmemagazine/posts?fields=name,message,full_picture,created_time,shares,likes.limit(1).summary(true),comments.limit(1).summary(true),insights.metric(post_impressions_unique)&access_token=USER_TOKEN"
