// Integration methods explained

Sage Pay Form:

A simple encrypted form submission post from your website to the Sage Pay systems, the shopper is then transferred to our hosted payment pages  for the card details to be securely captured. This is the most basic method of integration available on our platform with your site only requiring a single post for the transaction to be processed. 

Sage Pay Server:

The Sage Pay Server method of integration allows you more control over the transactional process than the Form solution.  The Server integration still enables you to have the transactional process hosted on our platform. There is continuous channel of communication open between your site and our platform.  The Server method also enables our vendors the option to implement an “InFrame” into their site which embeds the Sage Pay payment pages on the vendors website.

Sage Pay Direct:

This solution gives you complete control over the transactional process including the hosting of the card details capture pages.  You are required to undertake complete developmental work of the entire payment process including the security and safety of the details that are captured.
