Setting up GitHub Actions Slack Notifications

For many engineering teams using GitHub, GitHub Actions has become an essential tool for continuous integration, continuous deployment, and monitoring workflows. Setting up GitHub Actions Slack notifications is an effective way to keep your team informed, with CI/CD updates and other key notifications delivered directly to Slack.

There are two main options to set up GitHub Actions notifications for Slack. The first is to use a customer GitHub Action integration in your repository, which leverages the Slack API and requires an OAuth token. This option allows your team to receive GitHub Slack pull request notifications and other automated messages. Alternatively, you can install an application with a user-friendly interface, such as Axolo, to easily configure Slack GitHub notifications for GitHub Actions pull request updates and more. This guide will explore both approaches so you can choose the best fit for your team's notification needs.

Why Send Slack Notifications from GitHub Actions?

Integrating GitHub Actions Slack notifications into your workflow is an essential step for engineering teams looking to streamline communication. With GitHub Actions notifications, you can keep your team up-to-date on everything from pull requests to build statuses without leaving Slack.

For example, setting up Slack notifications ensures that everyone involved in a project is alerted when there’s a new pull request, a status update, or an error. This kind of Slack GitHub PR notification provides real-time information, keeping everyone in sync without the need to constantly check GitHub.

Additionally, CI/CD notifications can improve workflow efficiency by automatically sending status updates or specific messages to relevant channels. By configuring GitHub action to send Slack message, your team will be able to see GitHub action status notifications directly within Slack, helping you respond faster to important changes. In short, GitHub Slack notifications are a powerful way to bridge communication gaps and ensure smooth, efficient workflows.

Three Open-Source GitHub Actions for Slack Notifications

During our research, we found several applications on the GitHub Marketplace to set up GitHub Actions notifications in Slack. Here, we focus on the top three open-source options, each with over 100 stars, that enable GitHub Actions notifications to be sent to Slack and streamline team communication.

Slack Notify

This application, created by rtCamp, has 1.1k stars on GitHub. In addition to Slack GitHub notifications, rtCamp developed two other GitHub Actions, PHPCS Code Review and Deploy WordPress, offering a range of solutions for automated workflows. The Slack notify action enables efficient GitHub PR Slack notifications for CI/CD updates directly in Slack channels, making it easier to monitor key status updates.

With a well-documented API, Slack notify also supports advanced features such as HashiCorp Vault integration, providing added flexibility and security for teams needing GitHub actions Slack notifications that fit into more complex workflows.

How to use it:

    - name: Slack Notification
      uses: rtCamp/action-slack-notify@v2
      env:
        SLACK_CHANNEL: general
        SLACK_COLOR: ${{ job.status }} # or a specific color like 'good' or '#ff00ff'
        SLACK_ICON: https://github.com/rtCamp.png?size=48
        SLACK_MESSAGE: 'Post Content :rocket:'
        SLACK_TITLE: Post Title
        SLACK_USERNAME: rtCamp
        SLACK_WEBHOOK: ${{ secrets.SLACK_WEBHOOK }}

From there, you can easily add this setup to any of your current GitHub Action and ask Slack notify to send you notifications in a dedicated channel.

GitHub Action for Slack

GitHub Action for Slack, developed by Nicolas Coutin and Christopher Lion, currently has 195 stars on GitHub. While it provides a straightforward way to set up Slack notifications, it’s important to note that this action is no longer actively maintained.

How to use it:

- name: Slack notification
  env:
    SLACK_WEBHOOK: ${{ secrets.SLACK_WEBHOOK }}
    SLACK_USERNAME: ThisIsMyUsername # Optional. (defaults to webhook app)
    SLACK_CHANNEL: general # Optional. (defaults to webhook)
    SLACK_AVATAR: repository # Optional. can be (repository, sender, an URL) (defaults to webhook app avatar)
  uses: Ilshidur/action-slack@2.0.2
  with:
    args: 'A new commit has been pushed.' # Optional

Sending GitHub Actions Notifications in Slack: Best Practices

Follow these best practices to keep your team aligned and informed with timely updates and essential details.

1. Use Specific Channels for Targeted Notifications
   Organize your GitHub Actions Slack notifications by directing them to relevant channels. For example, route GitHub Slack pull request notifications to dedicated channels for each project or team. This way, team members only receive Slack GitHub PR notifications that are directly relevant to their work, reducing noise and increasing focus.

2. Implement Conditional Notifications with slackapi/slack-github-action
   Using slackapi/slack-github-action, you can customize GitHub Actions notifications to only send alerts based on specific conditions, like build status or test outcomes. This lets you avoid unnecessary alerts while ensuring crucial updates, like errors or successful builds, are shared promptly.

3. Take Advantage of Customizable Tools Like action-slack-notify
   When you need more control over the appearance and details in your GitHub Actions notifications, consider using action-slack-notify. This tool allows you to personalize messages, enhancing the readability of GitHub Slack notifications for specific team needs.

4. Limit Notifications to Key Events Only
   To prevent overload, configure GitHub Actions notifications to trigger only on significant events. Set up GitHub PR Slack notifications to notify the team only on status changes, deployments, or high-priority updates. This keeps Slack free from minor notifications, ensuring the team stays focused on meaningful changes.

5. Use GitHub action to send Slack message for Direct Alerts
   When specific members need to receive critical updates, use these notification options to target them directly. This method is ideal for GitHub action status alerts or when immediate attention is required for certain GitHub Actions pull request updates.

6. Set Up Recap Summaries
   Use tools that allow you to set recap summaries of your GitHub Actions notifications in each PR channel. This provides the team with a summary of key updates, ensuring everyone has access to an overview of the project’s current state without having to scroll through individual alerts.

By following these best practices, you can keep GitHub Actions Slack notifications organized, relevant, and actionable, ensuring your team remains informed and focused on critical updates without being overwhelmed.
