[英]Add discount to Paypal payment
i'm using Paypal PHP SDK (in Laravel) to prepare a payment.我正在使用 Paypal PHP SDK(在 Laravel 中)来准备付款。 At the moment, that payment looks like this:目前,该付款如下所示:
{
"intent":"sale",
"payer":{
"payment_method":"paypal"
},
"redirect_urls":{
"return_url":"http://website.lab/payment/paypal/success",
"cancel_url":"http://website.lab/payment/paypal/cancel"
},
"transactions":[
{
"amount":{
"currency":"EUR",
"total":"223",
"details":{
"shipping":"0",
"subtotal":"273"
}
},
"description":"...",
"item_list":{
"items":[
{
"name":"product 8",
"currency":"EUR",
"quantity":21,
"sku":"w9",
"price":"13.00"
}
],
"shipping_address":{
"city":"...",
"postal_code":"...",
"country_code":"...",
"recipient_name":"...",
"line1":"..."
}
}
}
]
}
As you can see there are 50€ missing from the total to the subtotal and this cause this error如您所见,总计和小计中缺少 50 欧元,这会导致此错误
400{"name":"VALIDATION_ERROR","details":[{"field":"transactions[0].amount","issue":"Transaction amount details (subtotal, tax, shipping) must add up to specified amount total"}],"message":"Invalid request - see details","information_link":"https://developer.paypal.com/docs/api/payments/#errors","debug_id":"91d27597e954"}
Now looking to the Paypal SDK i'm not able to find any sort of method/Object that can tell Paypal to add a discount to the subtotal.现在查看Paypal SDK,我找不到任何可以告诉 Paypal 向小计添加折扣的方法/对象。
Any help will be appreciate, i really can't find any resource on the web that can solve this problem任何帮助将不胜感激,我真的在网上找不到任何可以解决这个问题的资源
You can add an item to your "item_list"
with a negative value to the transaction:您可以将一个项目添加到您的"item_list"
,交易值为负:
{
"name": "Discount",
"price": "-50",
"currency": "EUR",
"quantity": "1"
}
