如何取消PayPal(快速结帐)交易? [英] How do i cancel a PayPal (Express Checkout) transaction?

问题描述

我有一个使用Express Checkout处理付款的应用程序.

I have an application that uses Express Checkout to process payments.

在调用SetExpressCheckout(并让用户在Paypal页面上填写其详细信息)之后，以及在我实际使用DoExpressCheckoutPayment完成交易之前，我需要某种取消交易的方法.

I need some way to cancel a transaction after calling SetExpressCheckout (and having the user fill out his details on paypal's page) and before i actually complete it with DoExpressCheckoutPayment.

我在Paypal文档中找不到正确的方法，我只是让它超时还是需要进行一些API调用?

I can't find the right way to do it in paypal documentation, do i just let it time out or do i need to do some API call?

推荐答案

您只是让它超时.如果尚未调用DoExpressCheckoutPayment，则尚未执行任何操作.
令牌会在三个小时后自动失效.

You just let it time out. If you haven't called DoExpressCheckoutPayment yet, no action has yet taken place.
The token automatically expires after three hours.
