Re: X-Payments Virtual Merchant Refferer URL
I use xp with elavon virtual merchant.
xp payment config is quite simple:
Payment module: Virtual Merchant - Merchant Provided Form
set Initial transaction to auth & capture
merchantID is the same as elavon "accountID"
get the userid from elavon (I believe it is the same for all but for privacy I will not share it here)
get the PIN from elavon
terminal > advanced > system setup
Use HTTP Referrers [ unchecked ]
Auto Pend HTTP Transactions [x]
Auto Settlement [x]
EVERYTHING else is empty
