PayPal 按钮 - 添加自定义属性以从 IPN 侦听器发回

Question

我需要向我的 PayPal 按钮添加一个自定义密钥，该按钮从 IPN 侦听器返回一个值。我当前的 PayPal 代码如下。我可以将自定义 key/property 添加到 src url 或 paypal.Buttons 脚本吗？

<!DOCTYPE html>
<html>
  <head>
    <base target="_blank" />

     <script src="https://www.paypal.com/sdk/js?client-id=MyID_here&currency=USD" 
       data-sdk-integration-source="button-factory"></script>
     <script>
      paypal.Buttons({
        style: {
            shape: 'rect',
            color: 'gold',
            layout: 'vertical',
            label: 'paypal',

        },
        createOrder: function(data, actions) {
            return actions.order.create({
                purchase_units: [{
                    amount: {
                        value: '9.99'
                    }
                }]
            });
        },
        onApprove: function(data, actions) {
            return actions.order.capture().then(function(details) {
                alert('Transaction completed by ' + details.payer.name.given_name + '!');
            });
        }
    }).render('#paypal-button-container');
  </script>
</head>

<body>
  <div id="paypal-button-container"></div>

</body>
</html>

Answer 1

在 purchase_units 对象中，您可以提供 custom_id

记录在此处：https://developer.paypal.com/docs/api/orders/v2/#definition-purchase_unit

Answer 2

引用自 PayPal 文档：

custom_id string The API caller-provided external ID. Used to reconcile API caller-initiated transactions with PayPal transactions. Appears in transaction and settlement reports. Maximum length: 127

所以，我想应该是这样添加的：

            purchase_units: [{
                amount: {
                    value: '9.99'
                },
                custom_id: {
                    value: 'my_Custom_Value'
                }
            }]
