Php 为什么在使用此端点进行身份验证时Paypal API突然停止工作？（svcs.paypal.com/Permissions/RequestPermissions）

我正在向该端点发出请求

https://svcs.paypal.com/Permissions/RequestPermissions?requestEnvelope.errorLanguage=en_US&scope（0）=访问\基本\个人\数据和范围（1）=帐户\余额和范围（2）=事务\搜索和回调=callbackurl.com/{state\ u id}

我也在使用这些标题

array（'X-PAYPAL-SECURITY-USERID:'uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

一月初的某个时候，人们注意到有一个问题。API返回的响应为

(
    [0] => stdClass Object
        (
            [errorId] => 550001
            [domain] => PLATFORM
            [subdomain] => Application
            [severity] => Error
            [category] => Application
            [message] => User is not allowed to perform this action
        )

)

我目前正在使用Paypal提供的NVP/SOAPAPI凭据。我在文档或变更日志中找不到任何使我相信API中有更新或不推荐的内容。
不允许用户执行此操作。
看起来像是权限问题。您可能需要联系Paypal。
