Iwá Duarte Yup, I've run into that issue as well. Not enough tags. I created these articles and added the tags I cared about manually. Then I used the API to get the tags of these articles to finally get their IDs. It's a workaround but it kind of worked for me

Hey Iwá Duarte there is a Hashnode API https://api.hashnode.com/. Unfortunately, it only takes Tag IDs. Therefore, you have to GET the tag from an existing article first to find its ID. Then you can include that ID in the mutation. I'm working on a repo to create articles from MD files using that API. Also, a new Hashnode API has been announced and they might change that.
