貝寶全額退款不工作

Question

我試圖發起全額退款貝寶API：

$header = Array(
    "Content-Type: application/json", 
    "Authorization: Bearer $token", 
); 

$ch = curl_init($aurl . "/v1/payments/sale/{$params['transid']}/refund"); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, '{}'); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $header); 
$res = json_decode(curl_exec($ch)); 
$code = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
curl_close($ch); 

我得到一個狀態碼400回這個消息：

["name"]=> string(19) "TRANSACTION_REFUSED" 
["message"]=> string(23) "Request was refused.{0}" 
["information_link"]=> string(76) "https://developer.paypal.com/webapps/developer/docs/api/#TRANSACTION_REFUSED" ["debug_id"]=> string(13) "e1df77fc1910c" 

部分退款工作與此代碼：

$header = Array(
    "Content-Type: application/json", 
    "Authorization: Bearer $token", 
); 

$ch = curl_init($aurl . "/v1/payments/sale/{$params['transid']}/refund"); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode(Array("amount" => Array("total" => $_POST['amount'], "currency" => $params['currency'])))); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $header); 
$res = json_decode(curl_exec($ch)); 
$code = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
curl_close($ch); 

PayPal says，全額退款是可能的一個空的JSON有效載荷，但這種不工作。任何人有想法？

您已經爲此交易完成了部分退款。當您嘗試再次爲同一交易完成全額退款時，交易將被拒絕。

Can not do a full refund after a partial refund
