Give the right reviewers access to the PR channel
When a review needs a room, invite only the reviewers and channel you explicitly name.
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
Invite users to a Slack channel
Invites users to an existing slack channel using their valid slack user ids.
Why this helps
Reviewers lose time when the discussion channel exists but access is missing.
- Reduce access-related delays
- Keep invitations scoped
- Report invalid or already-present users separately
Setup
Build it in a few focused steps.
- 1Connect GitHub and Slackbot once.
- 2Tell Notis to invite the supplied reviewer user IDs to the exact review channel for each new PR.
- 3Choose New Pull Request Created and a run-report channel.
- 4Test with one real PR, channel ID, user IDs, and explicit invitation authorization.
Questions about this workflow
Does GitHub username equal Slack user ID?
Not necessarily; supply exact Slack user IDs or resolve them separately.
Can it invite everyone on the PR?
Only users explicitly included in the authorized scope are invited.

Supported Triggers and Actions
Notis builds workflows that link GitHub to Slackbot. A trigger fires from one place; an action lands in another.
GitHub triggers
Slackbot actions
Recurring trigger

Branch Changed
Triggers when a GitHub branch changes. Monitors a specific branch for: - New commits pushed (head commit SHA changes) - Protection status toggled (branch becomes protected or unprotected) - Protection settings changed, including: required status checks and their enforcement level, admin enforcement, required pull request reviews (dismiss stale reviews, code owner reviews, approving review count, last push approval), required linear history, force push allowance, deletion allowance, conversation resolution, branch locking, and fork syncing.
Add a remote file
Adds a reference to an external file (e.g., google drive, dropbox) to slack for discovery and sharing, requiring a unique `external id` and an `external url` accessible by slack.
New Branch Created
Triggers when a new branch is created in a GitHub repository. Detects newly created branches. Deleted branches do not fire events.
Add a star to an item
Stars a channel, file, file comment, or a specific message in slack.
Check Run Status / Conclusion Changed
Triggers when a specific GitHub check run changes its status or conclusion. Monitors a single check run for changes to: status (queued, in_progress, completed, etc.), conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required), started_at, and completed_at.
Add call participants
Registers new participants added to a slack call.
Check Suite Status / Conclusion Changed
Triggers when a GitHub check suite changes its status or conclusion for a given ref. 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.
Add emoji
Adds a custom emoji to a slack workspace given a unique name and an image url; subject to workspace emoji limits.
New Code Scanning Alert Created
Triggers when a new code scanning alert is created in a repository. Fires an event for each newly created code scanning alert detected in the configured repository. Alerts can be filtered by Git reference, scanning tool, state, and severity. The payload includes the alert number, rule details, tool information, state, severity, and the location of the most recent instance.
