为什么添加项目会使Paypal Checkout返回错误? [英] Why does adding items make Paypal Checkout return an error?
问题描述
我正在尝试使用JavaScript SDK创建PayPal订单.如果PayPal返回非说明性400错误，我将无法添加商品.
I am trying to create a PayPal order using the Javascript SDK. I am unable to add items without PayPal returning a non-descriptive 400 error.
此标记可以正常工作:
return actions.order.create({
purchase_units: [{
description: "Stuff",
amount: {
value: '57.49',
currency_code: "CAD",
},
}],
application_context: {
brand_name: "MyBusiness",
shipping_preference: 'NO_SHIPPING'
}
});
我在其中添加金额明细和项目的标记不存在:
This markup, where I add the amount breakdown and items doesn't:
return actions.order.create({
purchase_units: [{
description: "Stuff",
amount: {
value: '57.49',
currency_code: "CAD",
breakdown: {
item_total: '57.49',
}
},
items: [{
unit_amount: '57.49',
quantity: '1',
name: "item 1",
}],
}],
application_context: {
brand_name: "MyBusiness",
shipping_preference: 'NO_SHIPPING'
}
});
我正在遵循此文档:
https://developer.paypal.com/docs/api/orders/v2/#definition-purchase_unit_request
https://developer.paypal.com/docs/api/orders/v2/#definition-item
我猜想我添加细分的方式行不通.但是规范暗示它是金额->细分.
I'm guessing the way I added the breakdown doesn't work. But the spec implies that it is amount -> breakdown.
推荐答案
完整的示例...保存到HTML文件，或仅复制purchase_units数组
