You need to extend the access token. See this answer http://stackoverflow.com/questions/...ess-token-for-facebook-page/20514503#20514503

 

you need manage_pages permission and after that you can do me/accounts to list all the pages you are admin of from there you can get page access_token using that token you can post on behalf of page cheers
