Create a plan, open it for editing and set its visibility to **Private**. Then, in the **Custom Users** section, add the username of each user you want to allow. Users you allow can see and subscribe to the private plan on the API's pricing page, even though it stays hidden from everyone else. Image Pn ## Blocking a user To prevent a user from subscribing to a plan, add them in the **Custom Users** section and click **Block**. Image 1 Pn > Blocking only prevents new subscriptions. A user who is already subscribed keeps their access — to end it, cancel their subscription from [Studio → Subscriptions](/studio/managing-subscriptions).
