To connect an existing AWS Lambda function to API Gateway, you provide the function name, API name, region, and deployment parameters. The workflow automates resource and method setup, Lambda proxy integration, permissions configuration, and stage deployment.

The best way to configure Lambda proxy integration is through an automated workflow that sets up the API Gateway resource and method, attaches the Lambda function, and deploys the stage. This ensures the proxy integration handles requests and responses correctly.

Yes, you can enable CORS and throttling when exposing Lambda functions as REST APIs. The connection workflow applies these production safeguards along with access logging and configurable authorization types to secure and harden your endpoints.

Yes, the API Gateway and Lambda setup supports both REST and HTTP APIs. You can create either API type and attach your existing Lambda function via proxy integration, allowing you to choose the appropriate API architecture for your serverless workload.

To configure authorization and API keys for a serverless API endpoint, the workflow enforces support for configurable authorization types and optional API keys. This secures the API Gateway stage deployment and controls access to the connected Lambda function.

Production safeguards needed when deploying Lambda functions behind API Gateway include CORS, throttling, access logging, and proper error handling. The workflow configures these protections across development and production environments to ensure reliable, scalable endpoints.
