Securing GraphQL APIs with Authentication and Authorization

Building a powerful GraphQL API is only half the battle; ensuring that only authorized users can access sensitive data is critical for any production application. This text-based course guides you through the fundamental principles of API security, showing you how to establish robust access controls from the ground up. You will learn how to verify user identities and restrict data access safely without sacrificing the flexibility of your GraphQL schema. Starting with core security definitions and foundational concepts, you will read through clear explanations of modern token-based workflows and cookie-based storage strategies. What you'll learn: Understand the core differences between authentication and authorization in a graph environment; Implement secure JSON Web Token validation workflows within your GraphQL resolvers; Configure HTTP-only, secure server-side cookies to prevent common web vulnerabilities; Design fine-grained authorization rules at both the schema and field levels; Apply modern security best practices, including token rotation and basic rate limiting; Write clean, testable security middleware to protect your API endpoints. The course begins with essential security terminology before transitioning into practical architectural patterns, schema design, and step-by-step implementation strategies. This course is designed for beginner-to-intermediate backend developers and web engineers who have a basic familiarity with GraphQL but want to master API security. No advanced cryptography or security background is required to get started. Begin your journey toward building production-ready, secure GraphQL APIs today.
