Microsoft Entra Workflow Approvals in Slack

The approval request lands in Slack. No switching tabs. No waiting. You decide in seconds and move on.

Microsoft Entra workflow approvals are powerful, but too often they live buried in the Microsoft interface. Teams lose speed chasing down requests. Integrating these approvals directly into Slack changes that. It brings identity governance actions into the same channel where your team works, chats, and resolves issues.

With the Microsoft Graph API, you can pull Entra access package assignments, pending requests, and custom workflows into Slack. Pair this with secure event handling and you can turn a simple Slack message into a full approval interface. Managers can approve or deny access packages, group memberships, and role assignments without leaving Slack—still respecting Entra’s audit log and conditional access policies.

A typical setup involves:

1. Configuring Microsoft Entra ID Governance to send workflow events.
2. Creating an Azure app registration for API authentication.
3. Using Graph API endpoints like /identityGovernance/accessReviews/decisions or /identityGovernance/accessPackageAssignments to fetch requests.
4. Posting these requests into Slack with interactive message buttons via Slack’s API.

Security is preserved because all actions funnel through Microsoft’s authentication. Slack acts as the notification and action surface, not the source of truth. Each approval in Slack triggers a backend function that calls Entra securely, updates the status, and confirms back to the requester immediately in-channel.

The result: approval latency collapses from hours to minutes. Governance stays tight. Teams keep moving.
