Hi there, (please, be cool, I'm a beginner),
I programmed an API by using a http node though which one I gather a structure "as JSON" format in the body.
These data contain two fields: deviceId and an object (including many rows) which this one could have different name depending kind of data.
I'm able to JSONify this one to use/parse it in a JSON.
My question is, as the name of the object (here reppercTEMPdegC) can be change following API request, how is it possible to extract this name?
Goal is, depending name, I would like to check number of row inside.
Example of other object name: reppercHUMIDITY_PERC, usageWATER_LIT, etc
