Hi all
A noob question
I have this unit that sends a JSON or XML file to a server which works fine (but a somewhat pricey solution) .
i would like to make a more simpel solution to this using node red.
I know that it should work but i just need a direktion how to parse the file and send a response back to the unit.
any help would be appreciated
