Php Magento-PayPal payment pro-10002安全标头无效错误

我正在尝试将Paypal payment pro集成到我的Magento网站中

每当我尝试测试事务时，它都会给我以下错误：

“10002（安全标头无效错误）”

---

有人能帮我吗，Thanx提前

你需要确保用户名/密码/签名正确无误

一些可能的错误： *结尾或开头的空格

---

*“I”或“l”（最好直接复制长字符串）

您看到这个答案了吗？已尝试联系PayPal pro。。在集成支付网关的同时，它们以各种可能的方式引导开发人员的支付。你应该联系他们。确保你的paypal帐户处于测试模式，并且你的API数据处于测试模式。
