My API KEY
I am being asked to enter my API KEY, Where do I find my CODE STATS API KEY? and what is it for?
What does this question have to do with the Notepad++ editor?
If it does have something to do with the editor, explain in detail how, and what steps you are taking in Notepad++ to see this message.
If it does not have something to do with the editor, then this forum is not the right place for your question.
