Membership Plans

Through membership plans it’s possible to restrict content and apply membership perks. Access can be granted upon product purchase. Member discounts for products can be applied as well.

Content can be universally restricted per membership plan, based on multiple post types and taxonomies via access rules. Access rules determine whether members or non-members have access to the content, and when access is granted to the member, as content can be dripped (scheduled).

Settings are found in the Membership Plans section in the WP admin panel › WooCommerce › Memberships panel.
Membership plans can be connected to Subscription products.
