Make Sure Reviewers See Every Review Request

When a reviewer is requested on a pull request, Notis posts it to Slack with the PR details.

Trigger

GitHub Pull Request Reviewers Changed

Triggers when the list of requested reviewers (users or teams) for a pull request changes — for example when a reviewer is added, removed, or re-requested. The payload includes the full current reviewer list (users and teams with details), which reviewers were added, which were removed, and the previous reviewer list for reference.

Action

Post message to channel

Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.

Why this helps

Review requests in GitHub notifications can be missed or delayed, bottlenecking code review and blocking teams.

  • Reviewers see requests in Slack where they actively work
  • Reduces review delays by making requests visible
  • Creates a record of who was asked to review

Setup

Build it in a few focused steps.

  • 1Connect GitHub and Slack to Notis
  • 2Tell Notis: 'Post PR review requests to Slack'
  • 3Describe the outcome: 'When a pull request reviewer is requested, post the PR title, link, and reviewer name to a Slack channel'
  • 4Select the trigger: Pull Request Reviewers Changed
  • 5Choose a Slack channel for review notifications
  • 6Test by requesting a review on a real pull request

Questions about this workflow

Can I post to different channels for different reviewers?

Yes. Create multiple automations targeting specific teams or channels.

What if we request reviews on draft PRs too?

By default it posts all review requests. Tell Notis to exclude drafts if you prefer.

Can I include the PR description in the Slack message?

Yes. Notis will include as much detail as you want to help reviewers understand what they're reviewing.
