The Complete Gateway is an online terminal that facilitates the acceptance of credit card and ACH transactions.  The gateway is also built to integrate with several POS systems including shopping carts through an API or Source Key.  

This article will focus on how to run a Refund transaction.  

Once logged into the Complete Gateway you will find the main dashboard with several options to the left.  These options include topics such as Dashboard, Transactions, Batches, Customers, Products, Invoices, Reports, etc.

When selecting the Transactions feature a new drop down will appear with the headings of New Order, Simple Charge, Auth Only, Refund and Voice Auth.  

Refund Transaction

Once logged into the gateway select the Transaction feature to reveal a sub menu. From here select the Refund option to bring up the Refund dashboard.  

If you are looking to refund a previous transaction you can find it by entering information pertaining to the original sale within the Search Transaction bar. 

If the credit card is available and you have a swiper or device connected to your computer, you can also select the Swipe button and slide the card through the reader.

If you recently ran the card, you can view the most recent transactions under the Recent Transactions menu.  Once the card is found you can select the Refund button next to the transaction to have the card refunded back for the original sales price.

Once you have requested a Refund on the transaction a confirmation will appear asking if you are sure you want to refund that transaction.

Once confirmed another confirmation will appear confirming the transaction has been refunded.
