如何在Paypal Express Checkout PHP中从沙盒模式继续进行？

Question

I have setup paypal express checkout system in my website from https://devtools-paypal.com/integrationwizard/

It's working fine in sandbox mode.

Now i would like to on live mode(Paypal). After change to

$sandbox=false;

I am getting the following exception:

SetExpressCheckout API call failed. Detailed Error Message: Security header is not validShort Error Message: Security errorError Code: 10002Error SetExpressCheckout API call failed. Detailed Error Message: Security header is not validShort Error Message: Security errorError Code: 10002Error Severity Code: Error

From the Paypal site - you need the live API credentials. If you haven't set up a merchant account, that is your next step. If you have, the credentials will come from you account settings.

Ready to Go Live? Get a merchant account and generate API credentials. In your code:

THIS ==> Replace the Sandbox API credentials with the live API credentials. In the paypalfunctions.php file, make sure to set the Sandbox variable to false this causes the code to use PayPal live site API endpoints.

DO NOT hardcode your API credentials. Manage your API credentials securely, such as loading the credentials from a secure key store or some other secure configuration.
