How to resolve "Failed Refund" error?

The "Failed Refund" error usually happens when the refund reason in Shopify doesn’t match Amazon’s required format or predefined requirements.

Check whether the refund meets Amazon’s policies and retry the process.

Since Amazon only accepts specific, case-sensitive refund reasons, mapping your Shopify refund reasons to the correct Amazon equivalents beforehand ensures smooth refund processing without errors:

1. Go to the CedCommerce Amazon app

2. Navigate to Settings → Order Settings → Cancellation and Refund

3. Enable “Map Refund Reason”

4. Match your Shopify refund reasons with the correct Amazon refund reasons

For example:

• Shopify: Customer Return → Amazon: CustomerReturn

• Shopify: Seller Refund → Amazon: GeneralAdjustment
