因此，过去几天我一直在尝试了解为什么在尝试执行此操作时会遇到错误。我试图使用相同的令牌两次调用CreateRecurringPaymentsProfile，但是仅成功创建了第一个重复配置文件，而第二个失败，错误代码为“ 11581，数据无效，配置文件描述无效”。我仔细阅读了文档here，其中说：“如果要创建多个定期付款配置文件，则必须为每个计划创建的配置文件调用一次CreateRecurringPaymentsProfile。”，因此，我知道这是可能的。我还看到this thread遇到了同样的问题，但是尽管应用了该解决方案，仍然出现错误。
我将逐步指导我提出的每个请求以及下面的答复。
首先，我致电SetExpressCheckout，并确保每个订阅都具有＆L_BILLINGTYPE0 = 和＆L_BILLINGAGREEMENTDESCRIPTION0 = 。
