These two layouts provide detailed information about orders, both regular (Order Details layout) and scheduled (Scheduled Order layout). The modifications you have to make to them are similar and are described below.
You have to add the Order Approvals widget to each layout. This widget allows an approver to approve or reject an order and provide comments when viewing an order’s details. Note that Order Approvals widget only appears in the storefront when an approver is viewing an order’s details. Otherwise, it is hidden.
You also must use the latest version of these widgets:
The Order Details widget or the Order Details with Additional Info widget on the Order Details layout.
The Scheduled Order widget on the Scheduled Order layout.
The updated versions of these widgets provide:
The reasons an order requires approval. If you are using the Order Approvals webhook to integrate with an external system, all the reasons returned by the webhook response are listed.
The approver name and comments, along with the rest of an order’s details, after the order has been approved or rejected.
A Complete Payment button for the shopper if an order has been approved but still requires payment.
An Add Items to Cart button for orders that have been rejected. This button allows the shopper to quickly add the items in the rejected order to a new cart, forming the basis for a modified order that will pass approval.
