Answer 1

In the above code you are sending request to version 1.6 while in XML data you have mentioned version 1.5 You are missing some parameters in xml data which is being sent and those missing data are mandatory. There are some key missing in the request section.

I have solved this as per uidai guide. But haven't got successful response as you didn't provided the some keys and some keys you have provided are invalid.
