API Gateway REST & HTTP APIs

API Gateway is a fully managed service that makes it easy to create, publish, maintain, monitor, and secure APIs at any scale. Think of it as a front door for your backend services.

REST APIs

REST APIs are the original API Gateway offering. They provide comprehensive features including API keys, request/response transformation using Velocity Template Language (VTL), caching, and throttling.

HTTP APIs

HTTP APIs are a newer, simpler option. They're up to 60% cheaper than REST APIs and offer built-in support for CORS, automatic deployments, and OIDC/OAuth2. HTTP APIs are ideal for serverless workloads.

Integrations

Both REST and HTTP APIs support integration with AWS Lambda, HTTP endpoints, and other AWS services. The integration type determines how API Gateway forwards requests to the backend.

API Gateway Glossary

REST API: The original API Gateway offering with comprehensive features including VTL transformations, API keys, and advanced caching.
HTTP API: A newer, simpler API type that's up to 60% cheaper with built-in CORS support and automatic deployments.
Stage: A named reference to a deployment of your API. Stages allow you to manage different versions (dev, staging, prod).
Route: A combination of an HTTP method and a resource path that maps to an integration backend.
Integration: The backend service that API Gateway connects to. Can be Lambda, HTTP endpoint, or other AWS services.
