PayPal IPN折扣变量

Question

我正在使用PayPal IPN处理我网站上的付款.我希望用户能够输入折扣代码和传递给PayPal并计算的价值(金额或百分比).

我一直在寻找网络,但似乎只能找到以下内容:

Use discount_amount_cart to charge a single discount amount for the entire cart.

Use discount_amount_x to set a discount amount associated with item x

Use discount_rate_cart to charge a single discount percentage for the entire cart.

discount_rate_cart - Applies to entire cart however, this variable will only work with the "Upload" Method. Not the standard Add to Cart variables.

在我的请求字符串中测试这些后:

...&discount_amount_cart=10&...

PayPal似乎不承认这个折扣.这在PayPal IPN中是否真的存在？

谢谢你的帮助!
