Just wondering how SagePay authorises credit card payments without leaving the website. EG: going through the Checkout wizard, the second page reads:
Payment gateway to work with existing internet merchant account:
Gateway: Sage Pay
Where will the payments be processed?
1. Remotely - process at provider's site. VSP Form
2. Notified - process payments through notification. VSP Server
I thought "2" would keep you on your website but now not sure. The above is a bit ambiguous. What does "process payments through notification" and how does it work in practice. I'm not seeing any pages created by the wizard to enter credit card details.
