How to Send GitHub Notifications to Microsoft Teams (and Slack) Simultaneously

GitHub's Multi-Platform Notification Problem

GitHub supports both Slack and Microsoft Teams as notification destinations. The GitHub app for Slack is well-maintained and handles pull request reviews, CI status, issue comments, and deployment events. GitHub also has a Teams app with similar coverage.

The structural problem is the same one that affects most native integrations: each destination requires separate configuration per repository. For an engineering organization with 20 repositories, connecting them to both Slack and Teams means 40 webhook configurations — 20 for Slack, 20 for Teams. When you add a new repository, it must be connected to both. When a notification rule changes, it must be updated in both.

For post-M&A engineering organizations where one team uses Slack and another uses Teams, this duplication extends further: engineering leadership needs notifications in Teams, developers need them in Slack, and some repositories need to notify both audiences simultaneously.

GitHub's Webhook System

Every GitHub repository and organization supports outbound webhooks. GitHub fires webhook events for: push, pull_request, pull_request_review, issues, issue_comment, workflow_run, deployment_status, release, create, and delete.

These webhooks can be configured at the repository level (Settings → Webhooks → Add webhook) or at the organization level (Organization → Settings → Webhooks) for all repos simultaneously.

Configure the webhook URL to point to SyncRivo. SyncRivo receives the GitHub event payload, parses it, and routes to Slack, Teams, Webex, Google Chat, or Zoom — or any combination simultaneously.

Setup (10 minutes per organization):

1. In SyncRivo, connect your Slack workspace and Microsoft Teams tenant via OAuth.
2. Create a Webhook source in SyncRivo. Copy the endpoint URL.
3. In GitHub, go to your organization Settings → Webhooks → Add webhook. Paste the SyncRivo URL. Select Content type: application/json. Choose which events to send — or select "Send me everything."
4. In SyncRivo, configure routing rules: pull request opened/merged → Slack #dev-team; deployment succeeded/failed → Slack #deployments + Teams #engineering simultaneously; release published → Teams #product for non-engineering stakeholders.

GitHub Event Routing by Audience

Pull request opened: Route to Slack for the development team. Engineers reviewing PRs work in Slack — direct notification to the review channel eliminates the need to watch GitHub notifications.

Pull request merged: Route to Slack #deployments and optionally to Teams if the merge is into a protected release branch. Triggers downstream awareness for teams monitoring deployment readiness.

Workflow run failed (CI/CD failure): Route to Slack #engineering with urgency. Failed CI on a main branch affects everyone; failed CI on a feature branch is scoped to the PR author. SyncRivo routing rules can distinguish by branch name.

Deployment status (succeeded/failed): Route to both Slack and Teams. Engineers need to know deployments succeeded; product managers and stakeholders in Teams need to know new releases are live. This is one of the highest-value cross-platform notification events — the audience spans technical and non-technical teams.

Release published: Route to Teams for product and business stakeholders who track feature releases. Route to Slack for engineers who need deployment context. Both audiences care about releases for different reasons.

Security alert (Dependabot, secret scanning): Route to a dedicated Slack security channel and to a Teams channel for security-conscious stakeholders or CISO. Security alerts should reach both the technical team that acts on them and the leadership that tracks the security posture.
