It would be great if we could hide an issue/PR comment using the GitHub REST API. Right now you can only delete a comment, why not hide it using the API?

Keen to have REST API support for hiding issue/PR comments as part of the existing "update an issue comment" endpoint.

For reference, it'd be handy to choose the reason for hiding, as shown in the UI below.

My particular use-case is for programmatic hiding of outdated bot-comments.

As a workaround one can currently use the GraphQL API through Octokit:

mutation {
  minimizeComment(input: { subjectId: "nodes.id here", classifier: OUTDATED }) {
    minimizedComment { isMinimized }
  }
}

You can get the subjectId with a query like this:

query {
  repository(owner: "foo", name: "bar") {
    pullRequest(number: 1) {
      comments(last: 100) {
        nodes {
          # Use this as subjectId
          id
          author { login }
          viewerCanMinimize
        }
      }
    }
  }
}
