Refunding an eBay order should begin in eBay's Resolution Center. This ensures that your customer refund is processed correctly and that your customer receives their money back or exchange.
If you're syncing your orders with a store connection, once the refund is completed on eBay, the eBay order within inkFrog is adjusted.
If you're using a Shopify or Bigcommerce store, the order is deleted automatically by inkFrog in either platform.
If you're syncing orders with Amazon for FBA, there is no action taken from inkFrog to Amazon regarding the refund and any updates necessary at Amazon would have to be manually performed.
