Stripe Payments

Turn your Celena shop into a card-accepting store without touching card data: the customer pays on Stripe's hosted Checkout page, your server only receives the result.

• Stripe Checkout Session per order — order lines are sent as price_data, so no products need to exist in Stripe.
• Test and live keys stored separately — prepare the live pair in advance and switch environments with one select.
• Signed webhooks — Stripe-Signature verified with HMAC-SHA256 and a 300-second replay window; unsigned calls get HTTP 400.
• Exactly-once settlement — every event id is stored, so retries and the browser return never mark an order paid twice.
• Events covered: checkout completed, async payment succeeded/failed, charge refunded, payment intent failed.
• Refunds from the admin — full or partial, with the order payment status and order history updated automatically.
• Payments log with order links, Stripe identifiers, environment, last error and net received per currency.
• Pay-later links — copy the payment URL for any unpaid order and send it to the customer.
• Automatic capture or manual hold, custom statement descriptor, configurable payment method types.
• Zero-decimal currencies (JPY, KRW, VND…) handled correctly; secrets never appear in HTML or logs.
