Sweden Payments (Stripe — Klarna)

Cancel a subscription. By default the subscription stays active until the end of the current paid period (fair to the buyer); pass immediate=true to cancel right now.

Create a payment link in SEK for Sweden via Stripe (Checkout Sessions). Buyer pays with cards, Klarna, Apple Pay / Google Pay — whatever is enabled on the Stripe account. Returns a hosted checkout URL the buyer opens to pay — payment completes automatically, no confirm step. Bring your own credentials via HTTP header (x-stripe-secret-key; free test credentials from dashboard.stripe.com never move real money). Money always flows buyer→Stripe→merchant; this service never touches funds.

Create a recurring subscription checkout link (monthly/yearly/weekly billing) via Stripe. The buyer opens the URL, enters their card once, and is then charged automatically every period until canceled. Amount is per billing period in the local currency major unit. Respects the same owner policy guardrails as payments (the per-period amount is checked before anything is created).

Check whether a Sweden payment (created by create_payment_link) has been paid. Queries Stripe directly — pull-based, no webhook needed. paid=true when status is PAID.

Check a subscription created by create_subscription_link. Accepts the session_id (cs_...) or subscription_id (sub_...). active=true when the subscription is ACTIVE or TRIALING; NOT_SUBSCRIBED_YET means the buyer has not completed checkout.
