Processing Request Parameters with AWS Lambda and API Gateway

Building modern serverless applications requires a solid understanding of how data flows from user requests to your backend services. This course guides you through the essential techniques for capturing, parsing, and processing HTTP request parameters—including query strings, headers, and POST request bodies. You will learn to configure API Gateway to route requests seamlessly to AWS Lambda functions and manage your infrastructure efficiently using the Serverless Application Model (SAM). What you'll learn: - Understand foundational serverless concepts, API Gateway integration types, and Lambda execution models - Parse query string parameters, headers, and path variables from incoming HTTP requests - Process POST request bodies and form submissions within your Lambda function code - Configure CORS, request validation, and response formatting for clean client-server communication - Deploy and manage your serverless resources using AWS SAM templates - Implement modern security practices, including basic input sanitization and error handling The course starts with foundational definitions of API structures and Lambda event payloads, then moves step-by-step through configuration, parsing techniques, and deployment workflows. Designed for developers new to serverless architecture, this text-based course requires no prior AWS experience, though basic familiarity with programming concepts is helpful.
