The code piece that reading file 

 

If '$IsObject(pStream) {
            Set tFilename = pStream
            Set pStream = ##class(%IO.FileStream).%New()
            Do pStream.Open(tFilename,,pTimeout,"UTF-8", .tStatus)
            If $$$ISERR(tStatus) Quit
        }

Thank you so much. You were very helpful.

Thanks for the answer. If i understand correctly, this specific line should be place inside REST API for make audit to work? So, if i don't have any access to the REST API code the desired audit is not possible?
