Authorize.net: Disable or Update Transaction IP Velocity Filter to Avoid Payment Failures

Cadmium is modernizing our Authorize.net integration across our Eventscribe product. While this is an overall benefit, this update will allow use of Authorize.net’s Fraud Detection Suite and may cause payment failures in your transactions depending on how the Transaction IP Velocity Filter is configured.

What You Need to Know About the Transaction IP Velocity Filter

The Transaction IP Velocity Filter in your Authorize.net account is designed to prevent fraudulent activity by limiting the number of transactions from a single IP address within a specific time-frame.

However, this filter can also block legitimate payments, leading to payment failures. This can happen because of the actions taken by the filter, such as holding the transaction for review, declining it, or placing it in a pending review state, which can delay or prevent legitimate payments from being processed. Cadmium will indicate a failure for any transaction that involves a “Decline  or “Hold” within Authorize.net.

To continue using an Authorize.net integration without any payment failures, we encourage our customers to disable the Transaction IP Velocity Filter in your Authorize.net account or update the settings.
