交易ID在响应onApprove时不可用

Question

从此处返回的$对象：

details

    // Render the PayPal button into #paypal-button-container
    paypal.Buttons({
        // Set up the transaction
        createOrder: function(data, actions) {
            return actions.order.create({
                purchase_units: [{
                    amount: {
                        value: '0.01'
                    }
                }]
            });
        },
        // Finalize the transaction
        onApprove: function(data, actions) {
            return actions.order.capture().then(function(details) {
                // Show a success message to the buyer
                alert('Transaction completed by ' + details.payer.name.given_name + '!');
            });
        }
    }).render('#paypal-button-container');

该ID与通知中显示的“交易ID”不同：

https://developer.paypal.com/developer/notifications/

这可能是什么问题？还是在通知中如何将{ "create_time": "2019-07-03T20:25:02Z", "update_time": "2019-07-03T20:25:02Z", "id": "2NE12348FF594456W" } 返回的id与details交叉引用？
