User Property
User name for communicating with Paypal.
Syntax
public String getUser(); public void setUser(String user);
Remarks
This property is required to post messages to the PayPal URL. This should not be the same username as your PayPal account login, but rather the name of the API service you've created in your account. If you allow PayPal to auto-generate the name, it is usually the first part of your email address plus "_api1." plus the last part of your email address. For instance, a PayPal Id of test@teststore.com would generate a user name test_api1.teststore.com.
Default Value
""
