在授权和捕获过程，当paypal收取佣金？

Question

我已阅读有关授权和捕获过程的文档，我有类似于案例1：

的内容

1-Your buyer orders a camera from your website.
2-Your buyer enters payment information and authorizes payment.
3-Send your buyer to PayPal using a hosted flow, specifying the variable paymentaction=authorization
4-PayPal initiates the authorization.
5-On day 29, you ship the camera and capture funds.

但类似的事情可能发生，案例2：

1-Your buyer orders a camera from your website.
2-Your buyer enters payment information and authorizes payment.
3-Send your buyer to PayPal using a hosted flow, specifying the variable paymentaction=authorization
4-PayPal initiates the authorization.
5-On day 25 due some reasons (customer had cancel his reservation for example) i void authorization.

当PayPal在案例1和案例2中收取佣金时？如果我在没有捕获资金的情况下取消对客户的授权，那么无论如何他都要支付Paypal费用吗？

Answer 1

交易费应该在Capture上，因为那时PayPal会知道实际从一个人转移到另一个人的金额。据我所知，取消授权没有任何费用，因为首先没有实际的资金流动。
