The Problem: Keeping Your Team Informed

Your team lives in Slack. Every deployment, every release, every bug fix—your team needs to know. But manually posting updates is time-consuming and often forgotten in the rush to ship.

The solution: automate Slack release notes directly from your GitHub repository. Every meaningful change gets communicated automatically.

Why Automate Slack Release Notes?

  • Keep everyone aligned - Engineering, product, support all see the same updates
  • Save engineering time - No manual status updates
  • Create accountability - Automatic record of what shipped when
  • Improve transparency - Stakeholders see progress in real-time

Method 1: Slack Webhooks (Basic)

Step 1: Create Slack Webhook

  1. Go to your Slack workspace settings
  2. Navigate to Apps → Incoming Webhooks
  3. Create a new webhook for your target channel
  4. Copy the webhook URL

Step 2: GitHub Actions Workflow

name: Slack Release Notes
on:
  release:
    types: [published]

jobs:
  notify:
    runs-on: ubuntu-latest
    steps:
      - name: Post to Slack
        uses: slackapi/slack-github-action@v1
        with:
          payload: |
            {
              "text": "🚀 New Release: ${{ github.event.release.tag_name }}",
              "blocks": [
                {
                  "type": "section",
                  "text": {
                    "type": "mrkdwn",
                    "text": "*Release ${{ github.event.release.tag_name }}*\n${{ github.event.release.body }}"
                  }
                }
              ]
            }
        env:
          SLACK_WEBHOOK_URL: ${{ secrets.SLACK_WEBHOOK }}

Limitation: This posts raw release content. Commit messages aren't user-friendly, and there's no AI enhancement.

Method 2: ReleaseFlow (Recommended)

ReleaseFlow transforms your code changes into professional release notes using AI, then delivers them to Slack automatically.

Setup Process:

  1. Connect GitHub - Install the ReleaseFlow app
  2. Connect Slack - Authorize your workspace
  3. Choose channel - Select where updates go
  4. Set schedule - Daily, weekly, or monthly

What You Get:

Instead of cryptic commit messages, your team sees:

📦 Weekly Product Update

New Features
• User preferences API now available
• Added bulk export functionality

🐛 Bug Fixes

• Fixed data sync delays

Best Practices

  • Choose the right channel - #engineering, #product-updates, or a dedicated #releases channel
  • Set notifications wisely - Don't spam; weekly summaries often work better than per-commit
