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 Void a transaction within the Complete Gateway.  

Once logged into the Complete Gateway you will find a series of tabs listed below the CG (Complete Gateway) banner on the screen. 

A Void can only be performed if the original sales transaction was ran during the same day and has not been settled or batched.  

To perform a Void go to the Batches tab and find the transaction that you would like to void.  Select the Details button to the left of the transaction.

In the Transaction Details screen you will find a Void Transaction option to the right of the screen, select this option.

A confirmation will appear asking if you are sure you would like to continue with voiding the transaction.  There is also an option to release the funds immediately back into the bank account.  This option submits a request back to the issuing bank requesting for the original funds being held by the sales authorization to be released back into the bank account.  It is up to the issuing bank on if they will release those funds or not.  Select the Confirm button.

Another confirmation screen will appear showing that the original sales transaction has been voided.
