The Memberful Integration allows you to limit posts to only users that are subscribed to one of your membership programs.
To authenticate, you'd need to create a custom application from your memberful dashboard and provide the following:
- The URL of your Memberful site. Looks something like https://YOURSITE.memberful.com.
- The client identifier
Once enabled, you can then either mark individual posts as protected from the posts editing screen, or mark the entire blog as private in the admin settings (Settings > Admin).
Check out the Demo to see how everything works without having to sign up.
