Introduction

Microsoft has officially announced the retirement of the Azure Active Directory (Azure AD) Graph API, with a phased deprecation culminating in complete shutdown by June 30, 2025. This transition necessitates that developers and IT professionals migrate their applications to the Microsoft Graph API to maintain functionality and leverage enhanced features.

Background

Azure AD Graph API has been a cornerstone for accessing Azure Active Directory services, enabling applications to interact with directory data. However, with the evolution of Microsoft's cloud services, the need for a more unified and robust API led to the development of Microsoft Graph. This API offers a single endpoint to access a vast array of Microsoft services, including Microsoft 365, Windows 10, and Enterprise Mobility + Security.

Key Timelines

  • June 30, 2023: Completion of the three-year deprecation notice for Azure AD Graph API.
  • August 31, 2024: New applications created after this date will be blocked from using Azure AD Graph APIs unless explicitly configured for extended access.
  • February 1, 2025: All applications, both new and existing, must be configured for extended access to continue using Azure AD Graph APIs.
  • June 30, 2025: Full retirement of Azure AD Graph API; all API requests will cease to function.

Implications and Impact

The deprecation of Azure AD Graph API signifies a shift towards a more integrated and secure API ecosystem. Applications relying on the legacy API must transition to Microsoft Graph to avoid service disruptions. This migration offers several benefits:

  • Unified Endpoint: Access multiple Microsoft services through a single API endpoint.
  • Enhanced Security: Improved security protocols and compliance features.
  • Expanded Functionality: Access to new APIs and features not available in Azure AD Graph.

Migration Steps

  1. Audit Existing Applications: Identify applications using Azure AD Graph API.
  2. Review Microsoft Graph Capabilities: Familiarize yourself with Microsoft Graph's features and endpoints.
  3. Update API Calls: Modify application code to replace Azure AD Graph API calls with Microsoft Graph equivalents.
  4. Test Applications: Ensure that all functionalities work as expected after the migration.
  5. Monitor and Optimize: Continuously monitor application performance and optimize as needed.

Technical Details

Conclusion

The retirement of Azure AD Graph API marks a significant transition in Microsoft's API offerings. By migrating to Microsoft Graph, developers and IT professionals can ensure uninterrupted service and take advantage of a more secure and feature-rich API environment. Proactive planning and execution of the migration process are essential to avoid potential disruptions and to leverage the full capabilities of Microsoft Graph.
