I am currently trying to create a module for Magento to show if the payment method used is Paypal Express via credit card or via Paypal account.
Digging through the files I come accross app/code/core/Mage/Paypal/Model/Api/Nvp.php
There is a line in Request/response for GetRecurringPaymentsProfileDetails where the code is:
protected $_getRecurringPaymentsProfileDetailsResponse = array('STATUS', /* TODO: lot of other stuff */);
What does this code do?
