Authorize.net 3.1 integration

Integrating Authorize.net into your UltraCart account

Very Important Integration Note

Turn Off Authorize.net Fraud Prevention Suite

UltraCart does not support the Authorize.net Fraud Prevention Suite. You must turn that feature off when integrating Authorize.net with your UltraCart account.

UltraCart sends out an automated email to merchant, if a transaction occurs that is held by the Authorize.Net fraud review system that tells them its not supported by UltraCart and instructs the merchant to turn it off.


For additional fraud prevention protection, please see the UltraCart Fraud Prevention tool.

The first set of steps are listed at Authorize.Net's web site.

Reviewing Transaction History of placed orders

When an order is placed that has not been successfully processed for payment, it will go into the Accounts Receivables department.  There, you can review the transaction responses in order to determine why the transaction failed. To see the transaction history of an order in the A/R department, navigate:

Main Menu > Operation > Order Management > Accounts Receivables


Click on the hyper-linked OrderID of the order (it should be color coded in pink signifying a "bad transaction"). Then scroll down below to the "Last Transaction" section. It appears below the "Payment" section and above the "Merchant Comments".

If there has been more than one transaction recorded, you'll also see a link that will take you to the complete transaction history.

When viewing the transactions the following authorize.net documents will provide you more details on the various response codes. These should help you determine the exact cause of the failed transaction:

Frequently Asked Questions

FAQ's - Click any question to reveal or hide the answer.)

 All of a sudden our orders are not processing, what could cause it to stop the credit card authorizations from working?

For various reasons, including higher than normal processing to excess chargebacks can cause the account to placed on hold. but the most common reason is accidental change of the Authorize.net transaction key. When you generate a new transaction key form within Authorize.net and existing transaction key's in use (such as the on inside UltraCart) will expirer after 24 hours. Failure to update the transaction key within UltraCart's configuration area will result in the transactions being rejected by the gateway due to a transaction key mismatch.

 I see UltraCart records the transaction ID for successfully authorizations within the "Transaction History" page of an order invoice. Can I use that to look the transaction up in Authorize.net?

Answer: Yes, you can look up all unsettled and settled transactions that have occurred within the last two years. See the following Authorize.net help doc for details: https://support.authorize.net/authkb/index?page=content&id=A714&actp=LIST

 If we configure UltraCart to require the "Company" field during checkout, is the company field passed to Authorize.net during the authorization?

Yes, the billing address company field will be passed along with the rest of the billing address and credit card details.

 Do you know circumstances why Authorize.net accepts or rejects transactions?

Yes. We track all the response codes that we get back from auth.net and there is a running list of what they mean here.

They send both an error and a response code, or multiples of they have a need.
