Can't view the key of a giveaway I have created.

Is it possible you forgot to enter a key and selected gift?

If you accidentally selected "gift" instead of "key" when creating the giveaway, I would just delete the giveaway and recreate it. If the giveaway is still running, support doesn't need to approve the deletion, the giveaway will be delete right away.

Or you could just contact the winner after it ends and send them the key. You can normally edit the key after the giveaway ends, but if you selected "gift" when it was created, I'm not sure if the site will give you that option, so you may have to contact the winner directly through Steam or email.

Hey
That happen to me too, you just select "gift" when you create the giveaway
You can't add the key for the moment but it will be possible when the giveaway is over no worry
