Checkout & Orders
Submit Checkout
Submit the active cart. The cart is re-priced and re-validated; the location's minimum order value is enforced (422 below it). If the account's approval policy requires it, an approval request is created (status `pending_approval`, no order yet); otherwise a draft order is created and the cart is emptied. `ship_to_address_id` (or an inline `ship_to`), `customer_po_number`, `requested_delivery_date`, `shipping_method_id`, `note`, and `payment_method` are accepted.
Estimate Checkout
