API Gateway is an important component of the AWS serverless stack and has great potential to enable low latency, low-cost, and secure applications. This course takes you through all aspects of the AWS API Gateway and contains ready-to-use code snippets to implement different patterns of serverless API development in AWS. 

You’ll learn core concepts and get hands-on experience with core API Gateway capabilities. You’ll also dive deep into data mapping and WebSocket APIs and build a fully functional multi-user chat application with WebSocket API. You’ll learn about various services that can integrate with the API Gateway. Throughout the course, you’ll use IaC to provision resources, coupled with an introduction to CloudFormation. You’ll conclude the course by building a fully functional chat application with a bot that listens to the conversation and sends random jokes when asked.

Through detailed lessons covering theoretical and practical knowledge, this course helps you master the AWS API Gateway service.

AWS API Gateway: The Unsung Warrior

## What’s the REST API?
The Representational State Transfer (REST) API is today’s most common and popular API specification. It’s popular because of its simplicity and extendability. Most web services exported by AWS are REST APIs. No wonder API Gateway provides us with solid support for REST API development.

## REST API in AWS API Gateway
Any REST API definition has three components, namely the URL, the HTTP method, and the definition for request/response payloads. Let’s see how we can implement it with the AWS API Gateway.

Open the “AWS Console - API Gateway” page to see the API we created in the previous chapter.
