#' Post an event with a result to the response endpoint

#' This function will first serialise the event result according to its class
#' by dispatching through \code{\link{serialise_result}}.The result of that
#' serialisation is posted **as is** to the response endpoint; this function
#' will not perform any JSON serialisation, for example.
