Body

I'd like to be able to start a new discussion from a webhook event, is this possible?

(I want to send Wiki updates to discussions)

I can't seem to find much searching for this specific scenario, I'm wondering if I would need to use actions maybe?

With the help of some AI, this seems to be working:

name: Wiki Update Discussion

on:
  gollum  # Triggers when the wiki is updated

jobs:
  post-discussion:
    runs-on: ubuntu-latest
    steps:
      - name: Create Discussion in Custom Category
        env:
          GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          REPO: ${{ github.repository }}
          CATEGORY_NAME: "Wiki Updates"  # Change this to your preferred category name
        run: |
          HISTORY_URL="/~https://github.com/${REPO}/wiki/_history"
          TITLE="Wiki Updated: $(date +'%Y-%m-%d %H:%M:%S')"
          BODY="A change was made to the wiki. See the latest updates: [Wiki Edit History](${HISTORY_URL})"

          REPO_ID=$(gh repo view ${REPO} --json id --jq '.id')
          CATEGORY_ID=$(gh api graphql -F repoOwner="${{ github.repository_owner }}" -F repoName="$(basename ${REPO})" \
            -f query='query($repoOwner: String!, $repoName: String!) { repository(owner: $repoOwner, name: $repoName) { discussionCategories(first: 10) { nodes { id, name } } } }' \
            --jq '.data.repository.discussionCategories.nodes[] | select(.name=="'"$CATEGORY_NAME"'") | .id')

          if [ -z "$CATEGORY_ID" ]; then
            echo "Error: Category '$CATEGORY_NAME' not found. Check the category name in your repository."
            exit 1
          fi

          gh api graphql -F repositoryId="$REPO_ID" -F categoryId="$CATEGORY_ID" -F title="$TITLE" -F body="$BODY" \
            -f query='mutation($repositoryId: ID!, $categoryId: ID!, $title: String!, $body: String!) { createDiscussion(input: {repositoryId: $repositoryId, categoryId: $categoryId, title: $title, body: $body}) { discussion { url } } }'
