Under the menu item Transactions you will find an overview of your transactions in their different stages: Pending, Completed etc. See payment status explanation for more information.

Transaction list

Notice: It is possible to capture or cancel the full amount of one or more transactions directly from the list in the overview.

Actions in the transaction list

To complete or cancel individual transactions for the entire amount, use the buttons that appear on the right side of the list when the cursor is moved over the transaction in question.

If more than one transaction is selected (via checkmarks in the left side of the list), a general set of buttons appears at the top of the page, allowing you to capture or cancel the selected transactions.

Refund in the transaction list

Once a transaction has been completed, it can also be refunded via the overview if the full amount is to be refunded.

Click on the transaction number next to a given transaction to go to the details page for that transaction. This page contains general information about the transaction and the transaction history log, as well as the option to make partial withdrawals and partial refunds.

Transaction details

If you do not want to capture the full amount but make a partial capture, use the Capture transaction button. You will then be presented with a dialog where you can enter the desired amount to be captured. The partial capture will then appear in the list of completed transactions.

Capture transaction

Notice: It is only possible to capture an amount less than or equal to the original amount authorized on the transaction. It is not possible to capture more than the cardholder has authorized when the transaction is created.

If you want to permanently change the transaction amount, you can use the Change amount button. This function can be used in special cases, e.g. if the system connected to OnPay requires this.

Change amount of a transaction

Notice: This change is permanent and it is only possible to enter a value less than or equal to the amount approved on the transaction.

It is also possible to partially refund a transaction that has been completed. This is done by clicking the Refund transaction button (only appears if the transaction has been completed). Here you will again be presented with a dialog that allows you to specify the amount to be refunded:
