Running a Test Credit Card Transaction with Authorize.net

Place a test order through the Magento Admin

After Submitting the order you will notice the following comments added to the order indicating that the order has been authorized.

Verify that the transaction is showing up in your Authorize.net Account

You can Void this Authorization from within the Magento Admin by clicking on the Void button.

Note: Void will void the payment and leave the order still in a processing state requiring a payment method

The Order Comments on the order now show that the Payment Authorization has been Voided.

In Authorize.net we see that this transaction has been Voided

Note: If a credit card transaction has been Captured it can NOT be voided. Instead a Credit Memo must be issued which will create a separate transaction refunding the money.

If you which to Cancel the order completely then click on the "Cancel" button


Note: if you are having trouble getting Authorize.net to work through Magento it is a good idea to run a test transaction through Authorize.net Virtual Terminal
