2001 REJECTED: The Authorisation was Rejected by the vendor rule-base.
Explanation:
You will receive this error message when a transaction has been rejected due to either your AVS/CV2 rulebase or the customer has had three failed attempts to correctly enter their card details. The latter rulebase is set up as default on all Sage Pay accounts.
Solution:
The transaction would have failed due to the fraud rulebase which you would have set up onto your account. The only way to prevent this from happening, would be to remove or relax your current rulebase, however, this would apply to all your transactions.
