我正在尝试将 PayPal 模块集成到我们基于 osCommerce 的站点中 - 一个使用 PayPal DoDirectPayment (SOAP) API 通过 PayPal 执行信用卡授权/付款的插件。到目前为止，我有：
- 安装模块并让它工作
- 在启用 PaymentsPro 的 PayPal 沙盒中设置商家帐户
- 使用信用卡在 Sandbox 中创建买家帐户
- 已验证我们网站上的帐单地址与存储在 PayPal Sandbox 中的买家帐户的信用卡地址相匹配
我能够一直进行结帐流程；但是，每次交易失败时都会出现以下错误消息。
无效数据 (10540)
由于地址无效，无法处理交易。
我已经使用步进调试（通过 XDEBUG）来验证结帐表单中指定的地址信息是否已传递到 cUrl 请求中。在发送前不久出现的 SOAP 请求下方查找：
注意潜在的敏感信息已被更改；但是，我直接将 PayPal Sandbox 中的地址与我们网站上的地址进行了比较——它们是相同的，并且符合此处找到的 API 文档中列出的字段规范。第 42 页及以上

这个问题（无法使用 PayPal 模块处理交易）表明 SandBox 存在等待可以解决的问题……但是我的帐户是在 19 日创建的，但我仍然收到相同的基于地址的神秘拒绝。
我还搜索了（沙盒上的 paypal 直接付款错误）和（Paypal 网站付款 Pro DoDirect 付款集成问题。由于商家配置无效，无法处理此交易）但没有发现任何用处。
任何帮助，将不胜感激。
