Build a REST API with AWS Lambda & API Gateway (Serverless Engineer Series Ep. 2)
In this episode, you'll learn how to expose your AWS Lambda function over HTTP using API Gateway.
We'll build a real REST API that supports GET and POST requests while learning how API Gateway integrates with Lambda.
What you'll learn:
✅ HTTP APIs
✅ API Gateway
✅ Lambda integration
✅ GET & POST endpoints
✅ Query parameters
✅ Error handling
✅ Resource policies
By the end, you'll have a live API running on AWS.
