Hi all, very very new to node-red here. I have a device that will POST data to an endpoint. I then need to parse out specific values, convert to ASCII, and encapsulate in a UDP or TCP configured unicast. It seems like I should be able to do this in node-red using an HTTP IN node. the properties in the POST have values and keys. I am able to get the data into node-red but I am not sure what to do next. I thought I needed to use the change node to parse out the value I want to send but I am not sure how to tell the change node what to replace the payload with. Am I approaching this correctly?
Show us the data coming from the http node and tell us what form you want to get it into. First, though, read the section in the docs on handling messages. Can't post a link at the moment but you should find it ok.

I ended up getting this to work with some JavaScript in a function node. Thanks for your help.
