In the "Orders" section in your HeidiPay portal you are able to manage your orders.
To initiate a refund, click on a specific order and click on "Refund". If you have an integration by API through your ERP, you can initiate a refund directly from your own system.
HeidiPay will then issue the refund and send a confirmation email to the customer. You will be able to track the progress of any request in the "Orders" section.
To file a dispute, please send an email to firstname.lastname@example.org quoting the payment plan ID.
