Serverless Backend with AWS Lambda & API Gateway · Lesson

Custom Domain Names & Edge Optimization

Configure custom domain names for your APIs and leverage Edge-optimized endpoints for improved global performance.

Your API's Own Address

When you deploy an API Gateway API, AWS provides a default URL. It looks something like https://abcdef123.execute-api.us-east-1.amazonaws.com/prod.

While functional, this URL isn't very user-friendly or brandable. This lesson shows how to use your own domain name!

Every API Gateway API automatically gets a unique endpoint URL. This URL includes a random ID, the AWS region, and amazonaws.com.

Example: https://{restapi_id}.execute-api.{region}.amazonaws.com/{stage_name}
It works immediately after deployment.
Great for testing, but not ideal for public-facing APIs.
