Return and Result url are essential

[bevennyamande]

• The Response object from Paynow is too vague. Since this is an API why not make this a json response with all the information on success?
• Since most applications using this API would be web based i think the return and result urls are essential not optional.
  -- Paynow should redirect the client to the return url automatically on success on the url set by the merchant
  -- Paynow should sent results of the transaction to the mercant's results url or portal whichever way h/her backend is configured
• Create two methods separate ie for mobile payments why should i select the method for now? Why not make it an attribute of the Paynow object.
