Error in getting Graph API Explorer page access token?

Question

Facebook

When I try to get a page access token, I get the following. What could be the reason?

Answer 1

To be eligible to query manage_pages , you need to pass a validation. To do this, you will need to prove to Facebook that this permission is really needed and show how it is used (make a screencast ). Practice shows that English-language verification requests are processed faster.
See Application Verification section .
