How to:

1. Capture
   • When "Autocapture" is set to "1", the orders are captured automatically (set to Paid)
   • When "Autocapture" is set to "0" you can capture the order manually from Quickpay merchant dashboard and then create a transaction for the invoice, in the "Add Payment" tab (invoice details view) (use payment id from Quickpay merchant dashboard).
2. Refund:
   • To refund an order you can use Refund tab from the invoice (only if the order has been captured previously).
3. Cancel:
