Overview

A container for the response from PayPal. Each call to PayPal returns a generic set of information as well as a specific set for the call. For more information please refer to PayPal NVP API Developer Guide and Reference.

To use retrieve information in the response, call the corresponding name of the object. For example, all responses from PayPal includes the field ACK. To get the data for this field:

if response.ack == 'Success' then
 # do your stuff
end

This is because this class uses a meta-programming trick with method_missing to redirect all known method calls to its internal hash data structure.
