Developing REST APIs with Amazon API Gateway

Amazon API Gateway acts as a front door for applications to access backend services like Lambda, EC2, DynamoDB, or S3 via HTTP/REST/WebSocket APIs.

✅ Example Use Case: Newsletter Subscription (API Gateway + Lambda + SES)
📌 Scenario:

You want users to subscribe to your newsletter through a web form. When they submit, their email is:

validated and stored,
a confirmation email is sent.
💡 Tech Stack:
Frontend: HTML form (with email input)
API Gateway: Receives POST requests
Lambda: Handles logic (validation, storage, email sending)
Amazon SES: Sends confirmation email
(Optional) DynamoDB/S3: Stores subscriber info
🧭 Flow:
User fills form → clicks Subscribe
POST request sent to https://api.example.com/subscribe
API Gateway receives the request
Triggers Lambda function
Lambda:
Validates the email
Stores in DynamoDB or S3
Sends confirmation email via SES
Response sent back to user: "Thank you for subscribing" AWS,AWS Certification,Amazon Web Services,AWS Amazon,AWS Certified,AWS Training,AWS tutorial,Amazon AWS,What is AWS,Getting started with AWS,Amazon AWS tutorials,AWS Fundamentals,free aws,free aws tutorials,AWS Cloud,AWS Exam,AWS Practice Tests,Cloud Computing,Cloud Technology,AWS Jobs,AWS Services,API,Amazon API,amazon api gateway,Application Programming Interfaces,HTTP API,REST API,WebSocket API technical tutorials,technical training,technology,amazon web services,aws for beginners,amazon api gateway,aws api gateway,aws lambda and api gateway,apis for lambda,api gateway get method lambda function AWS,Amazon Web Services,Cloud,cloud computing,AWS Cloud,Amazon API Gateway,dr matt wood,awslaunch,Swagger definitions,AWS Management Console,CLI,SDK
