Order Processing

Authorization Failures

Authorization Failures

When a customer tries to buy something in your store with a credit card, the data is sent to your payment processor, such as Chase Paymentech, or Authorize.net. Your payment processor runs a series of checks to see if the credit card is valid, and then authorizes the card for use. See Types of Payment Modules for more information.

In 9.0005.3, Miva Merchant added several features to protect your store against credit card fraud. One of these feature is the Authorization Failures tab. In this tab you can:

To Manually Add an IP Address to Your Blacklist

  1. In the Order Processing > Authorization Failures tab, select a row and click Blacklist.
  2. In the Blacklist IPs dialog box, enter an expiration, and click Blacklist.

Blacklists IPS

As long as this IP address is on your blacklist, all attempts to use a credit card from this address will be ignored. When the expiration date is reached, the IP address is automatically removed from your blacklist. The customer at this IP address will be able to submit credit card authorization attempts in your store again.
