WebRequest.Entity to API 2.0

Hi,
I would like to transform a WebRequest

 Dim POSTParams() As String = Request.Entity.Split( "&" )

to the new API 2.0:

 Var POSTParams() As String = ...

Please, does anybody can help me?
What to use instead of “Entity”?

Kind regards,
Clemens

QueryString see https://documentation.xojo.com/api/web/webrequest.html#webrequest-querystring

Actually… Entity is now Body.
