[akashtilva]

hello,

i'm calling /admin/api/2021-04/orders/{{XXX_ORDER_ID}}/refunds/calculate.json by php curl with below data

====================================================================

	$data = '{
  "refund": {
    "shipping": {
      "full_refund": true
    },
    "refund_line_items": [
      {
        "line_item_id": 9776518856882,
        "quantity": 1,
        "restock_type": "no_restock",
      }
    ]
  }
}';

i also tested with 

$data = '{
  "refund": {
    "shipping": {
      "full_refund": true
    }
  }
}';

====================================================================

  $curl = curl_init();
		   curl_setopt($curl, CURLOPT_POST, true);
		   if ($data)
		      curl_setopt($curl, CURLOPT_POSTFIELDS, $data);

	curl_setopt_array($curl, array(
	  CURLOPT_URL => 'https://{{USER:PASS}}@{{MY_STORE}}.myshopify.com/admin/api/2021-04/orders/{{MY_ORDER_ID}}/refunds/calculate.json',
	  CURLOPT_RETURNTRANSFER => true,
	  CURLOPT_MAXREDIRS => 2,
	  CURLOPT_TIMEOUT => 0,

Hey @akashtilva 

Can you pass us an x-request-id response header for the call that isn't working?

Hello Kevin,

thank you for your response.

but i found the solution for the issue.

there was issue in curl arguments i passed.. due to which required data is not being transferred with POST request.

now below code is working perfect with any API call

<?php
$curl = curl_init();
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Content-Length: ' . strlen($data))
);
$result = curl_exec($curl);
curl_close($curl);
?>

Thank you.
