Your refund source covers any customer refunds you initiate. Like the account you use to receive payments, it can be a bank account or a gateway.
Bank accounts can refund purchases paid out to any bank account, but purchases paid out to a gateway must be refunded through the original gateway the transaction was run through. Any gateway account you add to receive payments with will automatically be added as a default refund source for purchases paid out to that gateway; you can’t manually add a gateway as a refund source.
By default the account you set up to receive payments with during the new account onboarding process is selected as your refund source, but you can change your refund source (or add multiple sources) by first navigating to your Payment accounts page.
Once there, click the Add account button to the right of the FOR REFUNDS header. If you have one or more debitable bank accounts that have not been added as a refund source, you can select them from the dropdown menu under Select a saved account. Click the Save button to add the account you’ve chosen from this list as a refund source.
If you want to add a new account instead, click the Or add new account link under the dropdown menu. Then, select whether you are adding a Commercial or Personal bank account and enter the required information. You can read more about where to find the required bank account information, and how to troubleshoot possible issues, in this article.
Finally, click the Verify bank account button to save your new refund source.
