Facebook request Dialog filter app_non_users not working

Question

I'm using facebook apprequest dialog, and filter friends who already using the app.

 FB.ui({method: 'apprequests',
  appid:'1234567890',
  filters: '['app_non_users']',
 }, requestCallback);

Anybody facing same issue? Please let me know how to fix this issue.

Answer 1

I think you need to write:

filters: ['app_non_users']

Answer 2

Actually it works, but it depends on person's privacy settings.

If user has 'Visibility of app' option set to 'only me' value, he/she is listed as 'non app user' even if he/she uses the app.

Simply said, if your friend does not share any info about app with you, you cannot get any info about this.

Seems reasonable to me ;)
