What is microsoft-graph-docs?

This repository holds the official documentation for the Microsoft Graph REST API, which is the tool developers use to tap into data and features across Microsoft 365 services. If your app needs to read someone's Outlook calendar, send a Teams message, manage OneDrive files, or look up a colleague's profile in Microsoft Entra (formerly Azure Active Directory), this documentation explains exactly how to do it. At a high level, the project is a collection of written guides and reference materials rather than a working application. It walks developers through the process of authenticating with Microsoft, constructing the correct web requests, and handling the responses so they can build integrations that work reliably. Microsoft recommends reading the content directly on their developer portal, but by hosting the source files on GitHub, they make it easy for the community to spot errors, ask questions, and propose fixes. Anyone building software that interacts with the Microsoft 365 ecosystem will rely on these docs. For example, a founder creating an app that automatically schedules meetings based on email requests, or a PM building a dashboard that tracks file activity across an organization's SharePoint sites, would reference these guides to understand what data is available and how to access it securely. It's the bridge between a product idea and Microsoft's underlying services. The notable thing about this project is its collaborative approach. Because all the documentation is open-source, developers can contribute directly by fixing typos, clarifying confusing explanations, or adding missing details. This keeps the guides current and accurate as Microsoft's services evolve, and it means anyone who spots a gap can help close it rather than waiting for an official update.
