Microsoft Graph API Foundations for Custom Applications

Modern organizations run on data, but connecting separate business tools can be a major challenge. The Microsoft Graph API solves this by acting as a single gateway to your data, users, and files across the entire Microsoft 365 ecosystem. In this text-based course, you will learn how to leverage this unified API to build custom, data-driven applications that boost productivity. You will transition from understanding basic endpoints to querying live services and managing secure authentication flows. What you'll learn: Understand the core architecture and foundational concepts of the Microsoft Graph API; Configure secure access using modern authentication protocols and permission scopes; Query user profiles, calendar events, and files using the Graph Explorer; Apply best practices for API rate limiting, error handling, and performance; Design custom application workflows that integrate seamlessly with Microsoft 365 services. The course starts with essential terminology and structural concepts before moving into practical query construction and authentication setups. You will read through clear explanations, explore realistic JSON payloads, and practice through written design exercises. This course is designed for beginner developers and IT professionals looking to integrate applications with Microsoft 365, with no prior experience with Microsoft Graph required.
