With this you can ingest the content of the request, process it in NiFi and send a response according to the results of your processing.</P><P>&nbsp;</P><P>If your only requirement is to ingest the content of the HTTP request, you should use a ListenHTTP instead.</P><P>&nbsp;</P><P>Cheers,</P><P>André</P><P>&nbsp;</P> Wed, 30 Mar 2022 10:58:24 GMT araujo 2022-03-30T10:58:24Z
