我正在使用 Adaptive Payments API 来创建新的并行支付。我正在阅读文档，但仍有一些问题:
是否有取消本次支付的API操作(显然是发送payKey)？
创建此付款时，我可以指定超时吗？
paypal 操作的默认超时时间是多少？
谢谢。
最佳答案
嗯，same question asked and answered在 PayPal X 开发者网络中:
At this time, there is not a way to cancel a paykey and a timeout value cannot be specified. The default timeout value for PayPal is 5 minutes (after being inactive) however a paykey is good for 3 hours. So if the user were to copy the redirect url (before logging in), that url (with paykey) would be good for 3 hours.
