I am wondering if it is possible to obtain an extended access token for facebook pages that do not have a facebook profile set as it's administrator. I see it is possible to create a facebook page without setting a user profile as the admin and having those pages auth with my app.
For pages that do have a facebook profile as it's administrator, I am able to extend the short lived access token when requesting the manage_pages permission. But I'm not if there is no user associated with it.
The documentation describes this process for extending page tokens.
Apps can retrieve a Page access token from Page admin users when they authenticate with the manage_pages permission. If the user access token used to retrieve this Page access token is short-lived, the Page access token will also be short-lived.
To get a longer-lived Page access token, exchange the User access token for a long-lived one, as above, and then request the Page token. The resulting Page access token will not have an expiry time at all.
