GET http://api.domain.com/1/users/ <-- retur         


        

Answer 1

1) On your design probably not. POST is not idempotent! So you should not use for the update or the delete, instead use PUT and DELETE from Rest

2) A better choice is to use the header Content-Type on the WS call, like: application/xml

3) Also on the header Content-Type u can use it: application-v1.0/xml

4) Not sure if it is the best, but probably the easiest way is to use HTTP's built-in authentication mechanisms in RFC 2617. An example: AWS Authentication
