Secure AWS API Gateway Integrations with AWS Services

Building scalable cloud architectures often means connecting your API Gateway directly to downstream services. Many developers default to writing custom Lambda functions just to pass data along, which adds unnecessary latency, cost, and maintenance overhead. This course teaches you how to bypass compute layers entirely by configuring direct, secure integrations between API Gateway and other services. You will learn to establish secure communication channels using identity and access management policies and custom payload configurations. What you'll learn: Understand foundational API Gateway integration types and mapping templates; Configure secure IAM roles and policies to grant precise service-to-service permissions; Build direct integrations with services like KMS, DynamoDB, and SQS; Map incoming HTTP requests to service-specific payloads using Velocity Template Language; Implement modern API security practices including token-based authorization and resource policies. This course starts with the core concepts of API routing and IAM security before guiding you through step-by-step written tutorials to configure, test, and troubleshoot direct service integrations. This course is designed for backend developers, cloud enthusiasts, and aspiring solutions architects who have a basic familiarity with cloud concepts but want to master secure, codeless integrations.
