To extract the paid or restricted content from a publisher's website, Marfeel needs full access credentials from the publisher.

The credentials can be a normal username and password or access tokens that the customer provides. This is so Marfeel's crawler can be authenticated and allowed access to extract all of the publisher's content to be replicated in their Marfeel Progressive WebApp (PWA). 

An ad-hoc content connector is normally developed by Marfeel to access and crawl Publisher's content.
