Get page_impressions from Facebook API

Question

Using the Graph API Explorer, I am trying to obtain the page_impressions metric (as described in the Facebook API Insights Documentation) for one of my pages. The actual value that I am looking for is the "Weekly Total Reach" number, found on the Facebook Insights page (https://www.facebook.com/userID?sk=page_insights).

What I've tried under Graph API:

• userID/insights/ - Gives some good info, but nothing about page_impressions

What I've tried under FQL Query:

• SELECT metric, value FROM insights WHERE object_id=userID AND metric='page_impressions' AND end_time=end_time_date('2012-12-26') AND period=period('week') - This returns an empty data set.

This same question (or very similar) has been asked a few times on stackoverflow, but I could not find an answer.

Answer 1

Turned out I was really just having issues with my Auth Token. When I used the following Graph API call it worked just fine:

/[pageId]/insights (thanks to Oleg, for the correction on pageId)

This gave me all the info I needed, including the page_impressions. And if I wanted just the page_impressions data:

/[pageId]/insights/page_impressions
