Episode notes

Welcome to another episode of Knowledge Nuggets with Mirko Peters. Today we're exploring Microsoft Graph Webhooks, one of the core building blocks for creating modern, event-driven Microsoft 365 applications. Almost every developer building with Microsoft 365 eventually faces the same challenge. How do you know when something changes? Whether you're waiting for a new user to be created in Microsoft Entra ID, a document to be uploaded to SharePoint, or an email to arrive in Outlook, the traditional solution has always been polling - repeatedly asking Microsoft Graph if anything has changed. The problem is that most of those requests return nothing, wasting API calls, increasing latency, and eventually leading to Microsoft Graph throttling. Microsoft Graph Webhooks solve this by completely changing the communication model. Instead of your application constantly asking Microsoft Graph for updates, Microsoft Graph automatically sends your application an HTTP request whenever something important happens.
