Wildcard JSON?

I’m having an issue with a http request. I’d like to create a IF ID is empty then do X. The challenge I’m running into is that the key wrapping the json info is changing on every entry. I’m wondering if there is a way to use a wildcard so I can say {{$json[“WILDCARD HERE”][“id”]}}

If there is just one root key you should be able to do this:

{{$json[Object.keys($json)[0]]["id"]}}

Thank you SO MUCH!
