Not sure exactly what you mean… as in what exactly you want to write to the file… but if you just want the payload - then just connect it to a file out node and configure that with a path and filename (if you want a fixed one to monitor) and see what happens.

Of course you may need to convert the payload in some way first - but you haven’t mentioned that.
