It’s one of the most commonly and widely used API specifications because of its simplicity and extendability. Most web services exported by AWS are REST APIs.

REST API with API Gateway

The REST API offered by the API gateway is based on a request/response model where the client sends the request, and the server responds to it synchronously. The Rest API in API Gateway had three main components: resources and methods, HTTP endpoints, and integrated services.

Let’s learn about them in detail.

Integrations

In API Gateway, integration refers to the process of connecting and coordinating the communication between an API and backend services or other AWS resources. Integration is a crucial aspect that defines how client requests to the API are handled, processed, and fulfilled by the underlying backend systems. We’ll learn more about integrations ahead.

HTTP endpoints

In API Gateway, HTTP endpoints in a REST API represent the URLs through which clients can interact with your API. These ...
