Membership area
A membership area is the private space only buyers or subscribers can enter. It holds the videos, materials and communities that are not public. In Brazil it is the standard name for the category.
The term spread among digital creators because it describes the model well: you are not selling a file, you are selling access.
There are two approaches. An external area lives outside the payment platform and gives you control over brand and domain. An internal one ships with the checkout: faster to set up, more limited to customise.
