AWS API Gateway FAQ
What is the difference between REST and HTTP APIs?
HTTP APIs are up to 71% cheaper and optimized for serverless and proxy workloads. REST APIs offer fuller API management features including request validation, caching, and private API endpoints. Choose HTTP APIs for simple Lambda proxies; REST APIs for complex API management needs.
Is there a free tier for API Gateway?
Yes. New AWS accounts receive 1 million REST API calls, 1 million HTTP API calls, 1 million WebSocket messages, and 750,000 connection minutes per month for the first 12 months.
Does API Gateway scale automatically?
Yes. API Gateway is fully managed and scales automatically to handle hundreds of thousands of concurrent API calls without any capacity planning.
What are the request size limits?
REST and HTTP APIs support payloads up to 10MB. WebSocket messages are limited to 128KB, metered in 32KB increments.
Can I use API Gateway without Lambda?
Yes. API Gateway can proxy requests to any HTTP endpoint, AWS services (like DynamoDB or S3 directly), or VPC-linked resources — Lambda is not required.
