Click Chat with Support, reference this article, and provide the following information so we can assist you:   
  • The method you are using to process the transaction (Blackbaud Merchant Services Portal for example)
  • Your external IP Address
  • The generic email address you use
With the above information, we can request your organisation's external IP address to be whitelisted. Entering a unique email address rather than a generic email will also have success. Please note that the FRAUD decline code can also be down to genuinely potentially fraudulent transactions.
