Process Refunds
To process refunds, follow Shopify's guide.
Do not process refunds from the Peach Payments Dashboard. The Dashboard cannot inform Shopify of the refund, so although you've refunded the customer, Shopify does not know that the customer has received a refund.
When the refund is complete, you can view the refunded transaction in the Peach Payments Dashboard.
