Serverless REST API With Authentication — Part 3 | AWS DynamoDB Full CRUD Python AWS Project

In Part 3 of this serverless series, we connect our authenticated REST API to DynamoDB and build a full CRUD backend. By the end of this video you will have a complete, production-pattern serverless application — create, read, update, and delete data in real time from a live browser interface. This is Part 3 of a 3-part series: Part 1 — Lambda + API Gateway →    • Serverless REST API With Authentication — ...   Part 2 — Cognito Authentication →    • Serverless REST API With Authentication — ...   Part 3 — DynamoDB CRUD + End-to-End Test (this video) What you will build: A notes application where authenticated users can create, read, update, and delete their own notes — all stored in DynamoDB and scoped to their Cognito identity so no user can ever see another user's data. What you will learn: How to create a DynamoDB table with partition and sort keys How to add least-privilege DynamoDB permissions to an IAM role How to perform CRUD operations in Python using boto3 How to scope database queries to authenticated users using Cognito sub claims How DynamoDB Query differs from Scan and why it matters How to build a complete live notes UI that talks to your real AWS backend AWS Services used: DynamoDB, Lambda, API Gateway, Cognito, IAM, CloudWatch Language: Python 3.14 Cost: Free — DynamoDB on-demand is free for tutorial-scale usage Watch the full series: Part 1:    • Serverless REST API With Authentication — ...   Part 2:    • Serverless REST API With Authentication — ...   Full Tutorial & Code: https://d3qqq77n3yfi4v.cloudfront.net...
