Captures, refunds, voids can be completed in Shift4Shop and these actions will automatically be reflected in Affirm. It isn't necessary to manage these functions separately in your Affirm dashboard.

While you can process orders in the dashboard, we strongly recommend using Shift4Shop to keep order status synced with Affirm. For more information on processing orders in Shift4Shop, refer to their documentation.
