how do I get an API key

Hello.

I am also new at this, but I saw a great tutorial today
that shows how to find the API key.

I have not done this yet myself, but it looks fairly simple.
You will need to go through the tutorials on this website:

I know the answer to your question is somewhere in the first
four tutorials.

Great tutorials.
Hang in there.
