Is there a way to delete labels for only opened issues?

Context is that I would like to remove the hacktoberfest label from open issues since the event is over. However from the docs, it seems that the issues API only have a route for deleting labels from all issues/PRs.

I'm guessing a way to do it is to find all issues, look through each of them to see if they are open and then use the PATCH API to update the labels for each of them. This is a little manual, so I'm happy to hear if there's better alternatives!

that's the way to go. If you have multiple repositories, it would make a good "remove labels from open issues" @octoherd script:

Thanks for clarifying! Then i'll make a octoherd script for it.
