Hi I want to implement credit() method using activemerchant. I am using PaypalExpress Gateway for that. When I show the Rdoc for Activemerchant, I have seen the parameters used in credit method credit(money,identification,options) I want to know what is the meaning of each parameters.
Money: is the amount in cents
Options: can be found in Class: ActiveMerchant::Billing::Gateway http://rdoc.info/github/Shopify/active_merchant/master/frames
