# Create Portal Session

`POST /billing/portal`

Open a Stripe Billing Portal session for the logged-in customer.

Used by the account page so paid customers can upgrade / downgrade
between Casual / Pro / Business, update card details, and cancel
in-app rather than emailing support. The portal's Stripe-side
configuration determines exactly which actions are allowed; this
endpoint just creates the session URL.

Free users are rejected with 403 — they have no active
subscription to manage. The pricing page is the right place to
drive an upgrade. The account page surfaces an "Upgrade" CTA
instead of a "Manage subscription" button for free users so the
403 path should never normally be hit by the UI.
