推荐答案
Security header is not valid 错误仅由两个原因引起:
The Security header is not valid error is only caused for two reasons:
凭据错误确保您已正确输入 API 用户名、API 密码和 API 签名.有时会发生在复制和粘贴过程中不小心添加了一个空格，这会触发此错误.在 SDK 或第三方购物车的管理面板中仔细检查此设置.
Wrong credentials Make sure that you've put your API Username, API Password and API Signature correctly. Sometimes it happens that during copy and paste there is accidently a space added, this would trigger this error. Doublecheck this settings in the SDK or in the admin panel of your third party shopping cart.
错误的端点如果您将数据发送到错误的端点，则会出现此错误.确保您将实时凭据和数据发送到我们的实时端点.当您想要测试您的商店时，请确保您使用我们的测试端点和沙盒测试帐户中的凭据.如果您使用第三方购物车，请确保您的商店在测试或实时模式下运行，以及您使用的凭据.
Wrong Endpoint This error would come up if you send the data to the wrong endpoint. Make sure that you sending the live credentials and data to our live endpoint. When you want to test your store make sure that you use our test endpoint and the credentials from your sandbox test account. If you are using a third party shopping cart, make sure that your store is running in test or live mode, regarding which credentials you are using.
您也可以在这里检查您的凭据:
You can check for your credentials here too:
对于现场
https://api-3t.paypal.com/nvp?&user=xxxxxxxxxx&pwd=xxxxxxxxxx&signature=xxxxxxxxxxx&version=70.0&METHOD=SetExpressCheckout&RETURNURL=http://www.paypal.com/test.php&CANCELURL=http://www.paypal.com/test.php&PAYMENTACTION=Sale&AMT=50&CURRENCYCODE=USD
对于沙盒

只需替换用户、密码和签名，然后在浏览器中输入即可.如果您正确输入了您的凭据，您应该会得到 ACK = SUCCESS.
Just Substitute the user, pwd and signature and enter in your browser. You should get ACK = SUCCESS if you have input your credentials correctly.
