Scenario: When you encounter a Payflowpro Verisign Billing error message “An error occured while processing your credit card. Please contact the merchant for further assistance.” when creating Sales Order from their Webstore in the Release Preview environment, check if you have received an email with the subject “Verisign v3 Billing Failure” and the said error message in the body
Solution: Check if the email also contains RESMSG: invalid vendor account in the email body.
After confirmation of the above error, try to re-enter your credentials in Setup > Accounting > Payment Processing Profiles for your Payflowpro profiles. Ensure that the password you entered in NetSuite is the Transaction password and not the Payflowpro login password.
If the error still persists after doing the above, contact Payflowpro support as they may need to provide you with a different credentials for test environments.
