In another post I got the answer that you only have to insert a few lines in the old code and that was it.

If you’re referring to this comment then I think you may need to re-read what I wrote (bold added to make that easier for you)…

@PeteKnight

With your code, it could be as simple as adding a couple of lines to the top of the sketch and inserting the new Auth token, but it’s impossible to say based on the information you’ve provided.
