Serverless REST API With Authentication — Part 1 | AWS Lambda + API Gateway Python AWS Project
Build a fully working serverless REST API on AWS from scratch using Lambda and API Gateway — written in Python. By the end of this video you will have a live endpoint on the internet and a browser UI to test it in real time.
This is Part 1 of a 3-part series:
Part 1 — Lambda + API Gateway (this video)
Part 2 — Add Cognito Authentication
Part 3 — Connect DynamoDB + Full End-to-End Test
What you will build:
A REST API that handles GET and POST requests, runs on AWS Lambda (Python), is exposed through API Gateway, and is testable live from a browser UI you build in this video.
What you will learn:
How to write and deploy a Python Lambda function
How to connect Lambda to API Gateway with proxy integration
How to deploy and test a live API endpoint
How to build a simple browser UI to call your live API
AWS Services used: AWS Lambda, API Gateway, IAM, CloudWatch
Language: Python 3.12
Cost: Free — stays within AWS Free Tier
Part 2 adds AWS Cognito authentication so only logged-in users can call your API.
Part 3 connects the API to DynamoDB for real persistent data storage.
