当使用gitHub源代码通过他们的API凭据或我自己的API凭据（已向PayPal验证其处于正常工作状态）使用PayPal时，会出现错误“ ACK： 失败，您没有权限进行此API调用。”我正在尝试使用“ DoDirectPayment” API调用。
https://github.com/paypal/merchant-sdk-php
我尝试了许多不同的API凭证，但最终调用了PayPal来让他们检查我创建的凭证。除了弄乱了源代码外，由于这些测试失败，我通过从gitHub重新下载项目重新设置了所有代码。

What account are you using? Is it a PayPal Payments Pro account, which is required for DoDirectPayment?
Also DoDirectPayment is an old integration; for direct credit card processing PayPal typically recommends using the Braintree Gateway instead: http://braintreepayments.com/
