I'm trying to Post notification to a user using the graph api, and I get this error:
"message": "(#15) This method must be called with an app access_token."
But I'm using an app access token for sure. Got it from -
https://graph.facebook.com/oauth/access_token?client_id={APP_ID}&client_secret={APP_SECRET}&grant_type=client_credentials
(See picture attached) http://img33.imageshack.us/img33/6486/h6zs.png
I was looking for help but didn't find anything that solve the problem . This thread did not help: Facebook notifications API: "This method must be called with an app access_token"
Can anyone tell me what can I do?
