We and SagePay cannot get this to work. Their Tech Support say we can use forms, remote server or direct. We would prefer direct, IE payment processing on our server. To do this where is the url "https://test.sagepay.com/gateway/service/vspdirect-register.vsp" in eCart?
At the moment we're getting INVALID. Can you point me to the right pages to code please.
Do I need to get it working in an "iframe" to work". If so, how does that work?
Should I change protx to sagepay sitewide?
