Hi team,

I’m creating the order refund request on rest API using curl in PHP. and getting an error

{ “errors”: { “transactions”: “expected Hash to be a Array” } }

This is my order refund function

function orderRefund($shopify, $order_id, $reason) {
              $refundcalarray = array(
				"currency" =>  "INR",
				"shipping" => array("full_refund")
			);
            $datarefundcal = array("refund"=>$refundcalarray);
            $datarefundcal = $shopify->rest_api('/admin/api/2024-01/orders/'.$order_id .'/refunds/calculate.json',  $datarefundcal, 'POST'); 
            $apioutputrefundcal = json_decode($datarefundcal['body'],true);
            $transactiondata = $apioutputrefundcal['refund']['transactions'];
            $refundtransactionarray = array();
            $refundtransactionarray['parent_id'] = $transactiondata[0]['parent_id'];
            $refundtransactionarray['amount'] = (float)$transactiondata[0]['maximum_refundable'];
            $refundtransactionarray['kind'] = 'refund';
            $refundtransactionarray['gateway'] = $transactiondata[0]['gateway'];
            $refundarray = array(
				"currency" =>  "INR",	
                "notify" => true,
                "note" => (string)$reason,
                "shipping" => array("full_refund" => true),
                "transactions" => array($refundtransactionarray)	    
			);
			  $datarefund = array("refund"=>$refundarray);  
            echo json_encode($datarefund, JSON_PRETTY_PRINT); echo "\n";

            $refund = $shopify->rest_api('/admin/api/2024-01/orders/'.$order_id .'/refunds.json',  $datarefund, 'POST');  
            $refund = json_decode($refund['body'], true);
            echo json_encode($refund, JSON_PRETTY_PRINT); echo "\n";
            return   $response = array( "message" => $refund['refund'] );
  }

This is my $datarefund Responce in json

{
    "refund": {
        "currency": "INR",
        "notify": true,
        "note": "test",
        "shipping": {
            "full_refund": true
        },
        "transactions": [
            {
                "parent_id": 7050521444583,
                "amount": 474.05,
                "kind": "refund",
                "gateway": "Gokwik UPI"
            }
        ]
    }
}

And this is the $response Error

{
    "errors": {
        "transactions": "expected Hash to be a Array"
    }
}

Where i’m doing mistakes?
