Answer 1

For reference ,I am posting the answer. I don`t know how json object are being mapped at backend. Finally, I found the solution afer so many tries. Its working for me. For the above posted request , just use a dot(.) along with inner json object for making keys as Follows.

1. For inserting data for firstName, Use "customerDetails.firstName" as key.
2. similarly for last name use "customerDetails.lastName" as key .
