Does Github issues API allow creating a new issue against a project rather than a repository?
Doesn’t every project belong to a repository?
Or do you want to add a note card to a project column instead of an issue card?
Yes, I had a project board where I wanted to add notes in one of its columns and then convert and assign them as issues to the correct repository. I thought this had to be done via the issues API itself, but turns out it we have to get the column id of the column in the project board and add a card to that column. I was taking the wrong approach earlier and my question was based on that, which probably makes it invalid.
