Connecting AWS Lambda and API Gateway for REST APIs

Building powerful backend services no longer requires managing physical or virtual servers, but a serverless function is only useful if your external applications can reach it. This text-based guide teaches you how to bridge that gap by connecting Lambda functions to API Gateway, transforming isolated code into accessible, production-ready REST APIs. You will start with the absolute fundamentals of serverless architecture, learning key terminology, core concepts, and how cloud resources communicate with each other. From there, you will progress to configuring triggers, managing HTTP methods, and securing your endpoints. What you will learn: Understand the core concepts of serverless computing, AWS Lambda, and API Gateway; Configure API Gateway triggers to route external HTTP requests to your Lambda functions; Set up RESTful resources, methods, and integration types; Implement modern security patterns, including API keys and basic authorization; Test and debug your API endpoints using clean, structured text-based exercises. The course begins with foundational definitions of cloud events and API gateways, then guides you through step-by-step configuration workflows, and concludes with best practices for monitoring and security. This course is designed specifically for beginners who are new to cloud integration and serverless development, with no prior AWS experience required. Start building your serverless API backend today.
