Allow Shopify store owners to automatically assign Discord roles to customers based on their membership purchases. Similar to Patreon’s functionality, this feature lets store owners create exclusive communities or tiered access in Discord, directly linked to Shopify memberships. Enabling this feature allows users to run their own Patreon-like membership platforms using your app, tapping into a large market of creators and community managers who want integrated commerce and community tools.
