AWS Lambda and API Gateway: Handling HTTP Events

Building modern serverless applications requires a deep understanding of how web requests travel from your users to your backend code. API Gateway acts as the front door, translating incoming HTTP requests into structured event payloads that AWS Lambda can process. This text-based course guides you through the mechanics of API Gateway event structures. You will transition from guessing event payload formats to confidently parsing headers, query parameters, path variables, and request bodies in your Lambda functions. What you'll learn: Understand the core differences between proxy and non-proxy integrations; Parse incoming headers, query string parameters, and path variables from event payloads; Handle JSON and multi-part request bodies safely within your Lambda code; Construct compliant HTTP responses with custom status codes, headers, and CORS settings; Apply structured logging to trace and debug event payloads during execution. You will start with the fundamental terminology of serverless routing and HTTP events. From there, you will read through practical payload examples, analyze standard request-response flows, and learn how to write clean, maintainable handlers. This course is designed for beginning developers and cloud enthusiasts who want to build serverless APIs. No prior experience with API Gateway is required, though a basic understanding of programming concepts is helpful.
