Paypal API:购物车项目金额的总和与订单金额不匹配
我正在使用 paypal express checkout API,但在设置数量时遇到了问题.以下是我的 URI 参数:
I am working with the paypal express checkout API and am having issues with setting the quantity. Below are my URI parameters:
$params = array(
'METHOD' => 'SetExpressCheckout',
'PAYMENTREQUEST_0_SHIPPINGAMT' => '0',
'PAYMENTREQUEST_0_TAXAMT' => '0',
'PAYMENTREQUEST_0_HANDLINGAMT' => '0',
'PAYMENTREQUEST_0_AMT' => "50.00",
'RETURNURL' => $this->_returnUri,
'CANCELURL' => $this->_cancelUri,
'HDRIMG' => $this->_logoUri,
'PAYMENTREQUEST_0_CURRENCYCODE' => 'GBP',
'L_PAYMENTREQUEST_0_DESC0' => 'Product description',
'L_PAYMENTREQUEST_0_NAME0' => 'Product name',
'L_PAYMENTREQUEST_0_AMT0' => "50.00",
'L_PAYMENTREQUEST_0_QTY0' => "2"
);
如果 L_PAYMENTREQUEST_0_QTY0 设置为 1,则过程正常.但是,将其更改为 2 并将 'PAYMENTREQUEST_0_ITEMAMT' => "100.00" 添加到数组会给我以下错误:
If L_PAYMENTREQUEST_0_QTY0 is set to 1 the process is fine. However, changing it to 2 and adding 'PAYMENTREQUEST_0_ITEMAMT' => "100.00" to the array gives me the following error:

L_SHORTMESSAGE0: Transaction refused because of an invalid argument. See additional error messages for details.
L_LONGMESSAGE0: The totals of the cart item amounts do not match order amounts.
L_SEVERITYCODE0: Error
我已经尝试了几个小时来修复它并放弃了.有人可以强调我需要做什么才能让它工作吗?
I have tried for hours on end to fix it and have given up. Can someone highlight want I need to do to get it to work ?
推荐答案
您缺少一个 ITEMAMT
.另请参阅我在 Paypal Express 结帐和运费中的回答错误,其中包含一个具有多个数量的工作示例.
You're missing an ITEMAMT
. See also my answer in Paypal Express checkout with shipping cost and error which contains a working example with multiple quantities.
