购物车中物品的量的总和不匹配SetExpressCheckout贝宝API次序的金额

Question

我尝试做如下设置快速结账的PayPal API请求：

VERSION=72.0 
METHOD=SetExpressCheckout 
LOCALECODE=AU 
RETURNURL=http://mysite.dev:1338/order/checkout-confirmation?id=1 
CANCELURL=http://mysite.dev:1338/cart 
PAYMENTREQUEST_0_PAYMENTACTION=Sale 
PAYMENTREQUEST_0_CURRENCYCODE=AUD 
NOSHIPPING=1 
L_PAYMENTREQUEST_0_NAME0=The Kitty Ring 
L_PAYMENTREQUEST_0_NUMBER0=2274 
L_PAYMENTREQUEST_0_DESC0= 
L_PAYMENTREQUEST_0_AMT0=50.00 
L_PAYMENTREQUEST_0_QTY0=4.00 
L_PAYMENTREQUEST_0_NAME1=GlassTop Digital Bathroom SLIM Scales Weight Body Fat Water Bone Muscle Calories 
L_PAYMENTREQUEST_0_NUMBER1=2283 
L_PAYMENTREQUEST_0_DESC1= 
L_PAYMENTREQUEST_0_AMT1=32.95 
L_PAYMENTREQUEST_0_QTY1=2.00 
PAYMENTREQUEST_0_ITEMAMT=265.9000 
PAYMENTREQUEST_0_HANDLINGAMT=0.00 
PAYMENTREQUEST_0_AMT=265.9000 

，并得到如下回应：

TIMESTAMP=2015-10-20T22:20:32Z

VERSION=72.0 
BUILD=18308778 
L_ERRORCODE0=10401

L_SHORTMESSAGE0=Transaction refused because of an invalid argument. See additional error messages for details.

L_LONGMESSAGE2=The totals of the cart item amounts do not match order amounts. 
L_SEVERITYCODE0=Error

我错过了什么？有人可以用新鲜的眼睛看到吗？在PayPal和eBay分离之后发生了哪些变化？

Answer 1

金额值格式不正确。它应该是：

PAYMENTREQUEST_0_ITEMAMT=265.90 
PAYMENTREQUEST_0_HANDLINGAMT=0.00 
PAYMENTREQUEST_0_AMT=265.90
