To incorporate order approvals on the Order Confirmation layout, make sure you are using the latest version of either the Order Confirmation widget or the Order Confirmation with Additional Info widget. The latest versions of these widgets include conditional text for two cases:
If the order is pending approval, a message describing the reasons the order requires approval is provided. If you are using the Order Approvals webhook to integrate with an external system, all the reasons returned by the webhook response are listed.
If the order will need payment after approval (in other words, the payment method used for the order is not a deferred payment method like invoice or cash), this message is provided: “After approval, you will need to provide payment information.”
