At times, there may be a need to refund/void an EFT for a customer. At this time, when necessary, the refund or void is processed within your Authorize.net account itself. Transactions that happen on the same day before settlement can be voided. If already settled, it will need to be refunded. You can only void the full amount, however, you can refund partial amounts if needed.
After logging into Authorize.net, click on Transaction Search on the top.
Choose Unsettled if the transaction has not settled. This will pull up a list of all unsettled transactions. To VOID an unsettled transaction, you will click on the Trans ID to the left to pull up the transaction.
In the new window that appears, you will click on VOID on the top left.
To perform a partial or full refund, you will either enter the customer's Account ID from Tan-Link under the Customer field ID Box, or you can enter the last 4 digits of the card number charged in the Credit Card/Bank Account field Credit Card #. If the transaction has already settled then select the date range.
Once you find the transaction, click on the Trans ID on the left side. In the new window that opens you can edit the amount for a partial refund or just click on REFUND to refund the full amount.
If you need to show this refund in Tan-Link, you can adjust the EFT transaction by going to Customers> Edit Transactions.
Here you can search for the Account ID and adjust it. Set Approved to 0 to mark the transaction as declined/refunded. This will mark the payment as DECLINED in the Customer's Account without adding a past due.
