Mark new pull requests as seen in Slack
A small, consistent reaction can tell the team that a new PR has entered the review queue.
Trigger
New Pull Request Created
Triggers when a new pull request is created in GitHub, matching the optional configured filters. Emits an event for each newly created pull request. Supports filtering by repository, owner/organisation, author, assignee, label, state, base branch, head branch, and draft status.
Action
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
Why this helps
Teams repeatedly ask whether a new PR was noticed, creating avoidable chatter.
- Create a visible intake signal
- Reduce duplicate check-ins
- Keep the exact message as the source of the marker
Setup
Build it in a few focused steps.
- 1Connect GitHub and Slackbot once.
- 2Ask Notis to add the authorized reaction to the supplied existing Slack intake message for each new PR.
- 3Choose New Pull Request Created and a report channel.
- 4Open one real PR with a supplied channel and message timestamp to test it.
Questions about this workflow
Will it post a new message?

Monitors all check suites associated with a git reference (branch, tag, or commit SHA) for changes to status (queued, in_progress, completed, etc.) and conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required, startup_failure, stale). Optionally filters by GitHub App ID.
