Episode notes

Welcome to another episode of Knowledge Nuggets with Mirko Peters. Today we're exploring Microsoft Graph Change Notifications, one of the most important capabilities for building modern, event-driven Microsoft 365 applications. Imagine your application needs to know whenever a new email arrives, a SharePoint document is updated, a Teams message is posted, or a user account changes inside Microsoft Entra ID. The traditional approach is simple - but inefficient. Your application repeatedly asks Microsoft Graph whether anything has changed. Most of the time the answer is "no," wasting API calls, increasing latency, and potentially triggering Microsoft Graph throttling. Microsoft Graph Change Notifications solve this problem by turning Microsoft 365 into an event-driven platform. Instead of continuously asking for updates, your application simply subscribes to the resources it cares about, and Microsoft Graph automatically notifies your application whenever something changes.
