So in order to get the insight data for my application I need the access_token with read_insight_data permission. However I don't want a user interaction during the process. Can I get my application's insight data with just application ID and secret?
thanks, Green
Okay I got it.
First, get client(AKA application) access token:
https://graph.facebook.com/oauth/access_token?client_id=${client_id}&client_secret=${client_secret}&grant_type=client_credentials
facebook will return something looks like:
access_token=XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Second Use that returned token you can get the application insight data:
https://graph.facebook.com/${client_id}/insights/?access_token=XXXXXXXXXXXXXXXXXXXXXXXXX
