 Q5. If given a choice , which one would you prefer to send params to the Get service , path params or query param ?Web Service2017-05-22 08:28:27

Ans. If the number of params is quite large , I would prefer to either split it with majority of it in query params or all in query params.

If the params are all mandatory , I would keep it as path params. If it's optional , I would keep it as query param so as to keep consistent base url.

If we don't require the param name , then they can be kept as path params as query params necessitates the usage of param name.
