The Billing customer portal is a Stripe-hosted UI for subscription and billing management.
A portal configuration describes the functionality and features that you want to provide to your customers through the portal.
A portal session describes the instantiation of the customer portal for a particular customer. By visiting the session’s URL, the customer can manage their subscriptions and billing details. For security reasons, sessions are short-lived and will expire if the customer does not visit the URL. Create sessions on-demand when customers intend to manage their subscriptions and billing details.
