Is this possible or will it be possible soon?
Thanks for the response. I couldn't figure out how to "redeem" the download key in the app or otherwise get the app to manage my game. If I go to the download page in the app, it just downloads the zip file and doesn't try to install it. I was able to generate and redeem a key outside of the app, but then I don't get updates or an itch api key passed to my game. What am I missing?
You'll want to make sure the keys you generate can be claimed. Since the app can only download from a user's account, it's not possible to use unlinked download keys. Once someone claims key to a restricted game then they'll be able to download it in the app as normal.
