manage_pages
The
manage_pages permission allows your app to retrieve Page Access Tokens for the Pages and apps that the app user administers. The allowed usage for this permission is to help people analyze or manage the posts, comments or Likes that are published to their Pages. You can also use this permission to publish content to Pages owned by the people who use your app. You may also use this permission to request analytics insights to improve your app and for marketing or advertising purposes, through the use of aggregated and de-identified or anonymized information (provided such data cannot be re-identified).
