REST and Hypermedia Concepts

Resource, Method, Request, Response

Amazon Gateway URL

The URL is determined by a protocol (HTTP(S) or WSS), a hostname, a stage name and, for REST APIs, the resource path.

Amazon Gateway API Base URL

The hostname and the stage name determine the API's base URL.

Amazon Gateway Hostname

https://{restapi-id}.execute-api.{region}.amazonaws.com

Amazon API Gateway Resources that Require Configuration Changes without Redeployment

Deployment (API Deployment)

A Deployment resource represents a REST API deployment in Amazon API Gateway. The Deployment is like an executable of an API represented by a RestApi resource. Once an RestApi is created, it requires deployment and association with a stage to make it callable by its users. To call a deployed URL, clients submit requests against the API's URL.

Resource updates require redeploying the API, whereas configuration updates to not.

Stage

Stage

An API stage is represented by a Stage resource and represents a named reference to a deployment, and at the same time, a snapshot of the API, including methods, integrations, models, mapping templates, Lambda authorizers, etc.

X-Ray Integration

API request latency issues can be troubleshot by enabling AWS X-Ray. AWS X-Ray can be used to trance API requests and downstream services.
