Create a **GitLab API** credential (a personal or project access token with\n   `read_api`) and attach it to *Fetch pipelines*.\n2. In *Fetch pipelines*, replace `PROJECT_ID` in the URL with your numeric\n   project id, URL-encoded path, or point it at your self-hosted host.\n3. Create a **Slack** credential with `chat:write` and attach it to\n   *Post digest*. Change `#engineering` to your channel.\n4. Run **Execute workflow** once to see the shape of the summary, then activate.\n\nSwap the GitLab call for the GitHub Actions or Bitbucket equivalent and the\nrest of the workflow is unchanged — only *Fetch pipelines* knows the provider.\n\nMIT licensed. Review it before you point production traffic at it.",
