客户在快速结账API

标签： php paypal express-checkout

当我让客户下了Paypal订单时，第一个订单就可以了。如果他们立即下了另一个订单，就会出现这个错误：

  

此令牌已成功完成交易。

我有什么想法可以清除它，以便他们可以立即下订单吗？

1 个答案:

答案 0 :(得分：0)

首先，使用一个TOKEN（在一个http请求上），您可以选择使用产品创建一个会话。如果您使用某些API方法（DoExpressCheckoutPayment，CreateRecurringPaymentsProfile等），您将使用此令牌！其他选项是使当前令牌的时间到期，但在这种情况下，错误消息将不同于＆＃34;此令牌已成功完成交易。＆＃34;

因此，您必须再次使用SetExpressCheckout API方法来获取另一个令牌。
