问题：
如何在使用PayPal restAPI执行付款之前更改发货金额
乜安志
我尝试将基于PayPal classic API的旧快速结账流程迁移到新的RestAPI，但在新流程中出现了一个问题：
如何在创建付款后和使用PayPal restAPI执行付款前更改发货金额？
创建付款后的请求：
{
"intent": "sale",
"payer": {
"payment_method": "paypal"
},
"transactions": [
{
"amount": {
"currency": "AUD",
"total": "100",
"details": {
"shipping": "10",
"subtotal": "75",
"tax": "15"
}
},
"description": "Transaction description.",
"item_list": {
"items": [
{
"quantity": "5",
"name": "Item Name",
"price": "15",
"currency": "AUD",
"sku": "sku"
}
]
}
}
],
"redirect_urls": {
"return_url": "http://localhost:56508/PaymentWithPayPal.aspx?guid=77096",
"cancel_url": "http://localhost:56508/PaymentWithPayPal.aspx?guid=77096"
}
}
执行付款前的请求：
{
"id": "PAY-12X5617352981972MKQ64KKA",
"transactions": [
{
"amount": {
"currency": "AUD",
"total": "101",
"details": {
"shipping": "11",
"subtotal": "75",
"tax": "15"
}
}
}
]

看起来REST不支持快速结账回调应用编程接口，该应用编程接口用于更新快速结账中的运输和税收总额。这并不奇怪，因为REST是针对移动开发者的，他们不一定想要额外的带宽。

您可以在创建付款后更改发货金额。您需要在执行付款呼叫中传递发货金额，它将覆盖您在创建付款时设置的发货。
创建付款时传入的请求：
{
"intent": "sale",
"payer": {
"payment_method": "paypal"
},
"redirect_urls": {
"return_url": "http://www.fff.com",
"cancel_url": "http://www.fff.com"
},
"transactions": [
{
"amount": {
"total": "20.00",
"currency": "USD",
"details": {
"subtotal": "18.00",
"tax": "1.00",
"shipping": "1.00"
}
},
"description": "This is payment description.",
"item_list": {
"items": [
{
"quantity": "3",
"name": "Hat",
"price": "2.00",
"sku": "product12345",
"description": "This is desc",
"currency": "USD"
},
{
"quantity": "3",
"name": "Hat",
"price": "2.00",
"sku": "product12345",
"description": "This is desc",
"currency": "USD"
},
{
"quantity": "3",
"name": "Hat",
"price": "2.00",
"sku": "product12345",
"description": "This is desc",
"currency": "USD"
}
]
}
}
]
}
在执行付款时：

如你所见，我在执行付款时已经通过了新的运费，这将是最终的运费。
