SERV NOT ALLOWED:512

“SERV NOT ALLOWED:512” is a general error that applies to the TransArmor settings for a Fiserv (First Data) account.

Through Datacap’s NETePay Hosted platform, a Universal End-to-End Encryption PAN key is available such that the same key can be used with any supported backend processor. But when using Datacap’s “classic” implementations, End-to-End Encryption is unique to each backend processor. For Fiserv, this is reflected in their TransArmor settings.

*If the ISO does not have direct access to these settings, they should reach out to their Fiserv Client Service Advisor
