• Order created — the order create trigger sends the customer confirmation (for website, subscription and Checkout As orders alike).
• Order refunded — customer refund email plus an admin copy; a full refund also creates the in-app notification Order Refunded.
• Order cancelled — in-app notification Order Cancelled (no customer email is sent by the cancel button).
• Pending authentication — Resend Pending Payment Email sends the customer a continue payment link and alerts your business email.

In-app notifications of type Orders (created, paid, cancelled, refunded) can be enabled in the Notifications settings, and the POS/Checkout As header can show a count of unread order notifications.
