GraphQL API Security: Authorization and Logout Resolvers

Building a functional GraphQL API is only the first step; securing it against unauthorized access is critical for any production application. This course guides you through the essential concepts of securing GraphQL endpoints, focusing on robust authorization patterns and secure session management. You will start by understanding core security terminology, the mechanics of JSON Web Tokens (JWTs), and how to safely handle user sessions. Next, you will explore modern best practices for extracting user identities and implementing granular authorization checks within your resolvers. What you will learn: Understand the fundamentals of authentication versus authorization in GraphQL APIs; Configure cookie-based session management to protect user credentials; Extract and validate user identities from JWT tokens within your resolver context; Build secure logout resolvers that properly invalidate sessions and clear cookies; Apply modern security practices including token rotation basics and defense against common web vulnerabilities. Through clear, step-by-step written explanations and practical code examples, you will progress from basic security concepts to implementing a fully secure authentication and authorization flow. This course is designed for backend developers and web enthusiasts who are new to GraphQL security and want to build production-ready APIs. No advanced security background is required to get started.
