With REST you sometimes chose to ignore the body in the reply to POST.

The REST convention for POST is that the request body contains the
new item to be added to collection and the reply body contain the
same item with any attributes added server side. But if the server
side is not adding any attributes, then there is no need to parse
the reply body as it then just contains the same as in the request
body.
