payumoney refund api in php - php

Question

In my mobile app, I have configured payumoney perfectly and its working great. Its just a case of refund. Below is the code in the php file which I call from the app:
include('../connection.php');
$orderid="AMD197";
$view_rs =$conn->prepare("SELECT * from tbl_payumoney_order WHERE orderid=:orderid");
$view_rs->execute(array(':orderid'=>$orderid));
$vfetch=$view_rs->fetch();
$merchantId="393463";
$paymentId= $vfetch['paymentId'];
$refundAmount= $vfetch['amount'];
$merchantAmount= $vfetch['amount'];
$aggregatorAmount= "0";
$refundType="1";
$data_string="paymentId=".$paymentId."&refundAmount=".$refundAmount."&refundType=".$refundType."&merchantId=".$merchantId."&merchantAmount=".$merchantAmount."&aggregatorAmount=".$aggregatorAmount;
//paymentId=123456&refundAmount=56&refundType=1&merchantId=765433&merchantAmount=6&aggregatorAmount=50
$ch = curl_init();
$url = "https://test.payumoney.com/payment/refund/refundPayment";
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, true); /* tell curl you want to post something*/
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_string); /* define what you want to post*/
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); /* return the output in string format*/
$headers = array();
$headers[] = 'Content-Type: application/json';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$output = curl_exec ($ch);
$info = curl_getinfo($ch);
$data = json_decode($output, true);
print_r($data);
$status= $data['status'];
$message= $data['message'];
$result= $data['result'];
I am getting this response:
Array ( [status] => -1 [rows] => 0 [message] => Something went Wrong
guid 3k4pcbv6kdqf405g0lut7id32m sessionId null [result] => [guid] =>
3k4pcbv6kdqf405g0lut7id32m [sessionId] => null [errorCode] => )
Can anyone suggest if I am doing anything wrong here?

Answer 1

Refund API doesn't work in test/sandbox environment.
Please find the Refund API below for live environment:
https://www.payumoney.com/treasury/merchant/refundPayment?merchantKey=merchantkeyvalue&paymentId=1234&refundAmount=10
Please pass the Merchant Key, Payment ID and Amount in Params and Authorization Header in Headers.

Something went wrong... error comes at PayUmoney's end due to 500, 502, 503 or 504
Server error in your App or Website according to PayUmoney API Documentation.
To know more about these HTTP Response Codes, you need to follow below link:
https://en.wikipedia.org/wiki/List_of_HTTP_status_codes
Also update your Curl to get more info in case of malfunction like below:
$output = curl_exec($ch);
if ($output === false){
// throw new Exception('Curl error: ' . curl_error($output));
print_r('Curl error: ' . curl_error($output));
}
If you still not sure about your issue, then its better to contact PayUmoney Support Team.
