Developer's Guide to Azure AD: Authentication for Office 365 and Custom APIs

Integrating applications with cloud services requires a rock-solid understanding of identity and access management. For developers working within the cloud ecosystem, mastering Azure Active Directory (Azure AD) is the key to securely connecting to Office 365, the Graph API, and custom endpoints. This course demystifies cloud identity from a developer's perspective. You will transition from guessing how authentication works to confidently configuring app registrations, managing permissions, and acquiring tokens to call secure APIs. What you'll learn: - Understand core Azure AD identity concepts, including tenants, users, and service principals. - Configure application registrations for web apps, single-page applications, and background services. - Apply OAuth 2.0 and OpenID Connect protocols to secure API communication. - Manage delegated and application permissions for Office 365 and the Graph API. - Implement secure token acquisition using the Microsoft Authentication Library (MSAL). - Design and protect your own custom APIs using Azure AD authorization. The course begins with foundational identity terminology before guiding you through step-by-step written explanations of real-world authentication scenarios and API integrations. You will learn by reading clear architectural breakdowns and analyzing practical code configurations. This course is designed for beginner developers and software architects new to cloud identity, and requires no prior experience with Azure AD or security protocols.
