It says to put parentId in orderTransactions as mandatory. I don’t know how to get parentId.

mutation returnRefund($returnRefundInput: ReturnRefundInput!) {
  returnRefund(returnRefundInput: $returnRefundInput) {
    refund {
      id
    }
    userErrors {
      field
      message
    }
  }
}

{
  "returnRefundInput": {
    "notifyCustomer": true,
    "orderTransactions": [
      {
        "parentId": "?????????????????????",
        "transactionAmount": {
          "amount": "6600",
          "currencyCode": "KRW"
        }
      }
    ],
    "refundShipping": {
      "fullRefund": true,
      "shippingRefundAmount": {
        "amount": "26000",
        "currencyCode": "KRW"
      }
    },
    "returnId": "gid://shopify/Return/5151096890",
    "returnRefundLineItems": [
      {
        "quantity": 1,
        "returnLineItemId": "gid://shopify/LineItem/12962798272570"
      }
    ]
  }
}

To get the parentId, you first need to fetch the transaction details of the order you are refunding. This can be done using the Order query of the Shopify Admin API. You should look for transactions associated with the order that have a kind of CAPTURE or SALE.
