过去5个小时我一直在搜索有关此事的信息,并且发现了很多不起作用的信息。我已成功使用setExpressCheckout API,获取详细信息并收取正常订单,但是当我想创建定期付款配置文件时,我总是会收到无效的令牌错误。我知道这不是一个无效的令牌,但我不知道该怎么做。
我目前正在使用PayPal的setExpressCheckout和createRecurringPaymentsProfile示例代码,但没有成功。
这是来自PayPal的我可笑的简化代码。

显然,这里的电子邮件,通行证和签名都是错误的。我的脚本名称是example.com/paypal/buy.php如果不清楚的话......
更新:我终于找到了有用的东西。我还没有漂亮的代码,但它确实至少经历过。 https://www.x.com/developers/paypal/forums/nvp/createrecurringpaymentsprofile-invalid-token-0
答案 0 :(得分:6)
你知道这一切吗?如果您未在SetExpressCheckout请求中包含结算协议(定期付款)信息,则会出现无效令牌错误的原因。
这是一个sample set,当这个问题出现时,我总是用它来向人们展示。请注意SEC中包含的BILLINGTYPE和BILLINGAGREEMENTDESCRIPTION。
