Limit customers to one subscription
Direct customers to manage their subscription when they already have one.
You can redirect customers that already have an active subscription to the customer portal or your website to manage their subscription. This redirection works with Checkout (including the pricing table) and Payment Links.
Stripe uses either the Customer object (if you provide it in the Checkout Session) or the email address to detect if a customer already has an active subscription.
