Could someone please let me know how to Upgrade Sagepay "SERVER" Integration method from protocol 2.23 to 3.00. I can see some technical documents from various forums but are always focus to upgrading Sagepay FORM Integration method only. Am using SERVER method to send transactions to sagepay.
Help me what are the fields that I should add/change over my code(transaction array), Or if any specific document for SERVER method that you suggest is most appreciated.
If you are going from 2.23 to 3.00 using Server, the most basic change you can get away is changing the VPSProtocol value. You do need to be aware that a few extra fields will be returned in the post to your notificationURL, so you need to be able to ignore (or capture the values) as appropriate.
Changing to 3.00 will keep you trading ;-) and also give you access to a few more features....
