Building Serverless APIs with AWS API Gateway

Serverless development is more than just writing Lambda functions; you need a robust, secure way to expose your logic to the world. AWS API Gateway acts as the front door for your applications, managing traffic, security, and integration seamlessly. This text-based course guides you from absolute beginner to confidently configuring your own serverless APIs. You will learn the foundational concepts of API design and transition into building, securing, and monitoring real-world endpoints. What you'll learn: Understand the core architecture of AWS API Gateway and how it interacts with serverless resources; Configure REST APIs and lightweight HTTP APIs to match your application's performance and budget needs; Implement secure authentication using API keys, Cognito, and modern JWT authorizers; Manage CORS, request validation, and data transformations directly within the gateway; Monitor and troubleshoot your APIs using CloudWatch logs and execution metrics; Deploy and version your APIs to support smooth development and production lifecycles. The course begins with essential API and serverless terminology before moving into step-by-step configuration workflows. Through clear written explanations and practical configuration examples, you will learn how to route requests, handle errors, and optimize your API performance.
