Set the http request node to output a parse Json object, then the string will be converted to an object.

Hi,

Thanks for your reply, I have checked for the same, but those Information is changing continuously as like FirstName, lastName, CardholderTypeUID etc according to RFID given to the user/employee.

So I just want to take this information, because not possible to mentioned in each object in function node with the Name and ID information it is changing continuously.
