Curl 我无法使用neteller API

{“错误”：{“代码”：“20005”，“消息”：“重复事务引用”}

我总是收到类似20005的错误。

该错误意味着您已经使用此“merchantRefId”创建了一个事务

“merchantRefId”字段应包含您进行的每笔交易的唯一值

$accessToken = $this->_netellerAccess();
                  $data_string = '{
                   "paymentMethod": {
                  "type": "neteller",
                  "value": "ashutosh12@avainfotech.com"
               },
               "transaction": {
                  "merchantRefId": "26434256",
                  "amount": 10,
                  "currency": "USD"
               },
               "verificationCode": "234124"
                   }';
                 $token=$accessToken['accessToken'];
                $ch = curl_init('https://api.neteller.com/v1/transferOut');
                curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
                curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
                curl_setopt($ch, CURLOPT_HTTPHEADER, array(
                    'Content-Type: application/json',
                     "Authorization: Bearer $token"
                        )
                );
               echo $result = curl_exec($ch);

只需将其更改为另一个随机值

"merchantRefId": "26434256"
