Stripe #

STOAR uses Stripe Checkout — a hosted payment page managed by Stripe. The customer is redirected to complete payment and then returned to the store.

Before the Stripe session is created, the cart is re-validated against current stock and prices. If anything has changed, the customer is notified before proceeding.

STOAR handles the following Stripe webhook events:

checkout.session.completed — marks the order as paid
payment_intent.succeeded — confirms payment capture
charge.refunded — updates the order status when a refund is issued through Stripe

Refunds initiated in Stripe are automatically reflected in the order record. Webhook handling is idempotent — if Stripe delivers the same event more than once, duplicate processing is safely ignored.

Mollie #

For EU/DACH stores, STOAR supports Mollie hosted checkout. The customer is redirected to Mollie to pay via iDEAL, Bancontact, SEPA, cards, and other local methods, then returned to the store. As with Stripe, the cart is re-validated against current stock and prices before the payment session is created.

Offline Gateways #

Bank Transfer, PayID, Interac e-Transfer, Cash on Delivery, and Invoice all follow the same pattern: a pending order is created immediately and the customer receives an email with their payment instructions.

No payment is collected by STOAR directly. The store operator confirms payment manually and updates the order status in the admin.

All gateway labels, payment instructions, and minimum/maximum order amounts are configurable per gateway.
