If you've ever wired up Lambda to API Gateway manually and forgotten the invoke permission or botched the CORS setup, this walks you through the complete procedure. It handles REST API creation, resource and method configuration, Lambda proxy integration, and the security bits that are easy to skip like throttling and access logging. Supports different auth types including IAM, Cognito, and custom authorizers. The troubleshooting section covers the usual gotchas like 502 errors from malformed proxy responses and permission denied issues. Honestly most useful as a checklist to make sure you didn't miss something rather than learning this from scratch.
