An application programming interface (API) is a set of methods that allow us to programmatically access a component. APIs can be built for different layers, such as the web (http/rest), database, and operating system layers, and so on. A representational state transfer (REST) API is an API that uses REST principles and HTTP protocol to build web APIs that can be programmatically consumed by clients over a network, such as the internet.
Amazon API Gateway is the primary service within AWS for building serverless, scalable, and secure REST APIs. It acts as a gateway between your application and the outside world. You only pay for the API calls and data that are transferred out, and you do not have to maintain a server. It also provides support for testing, authorization, API version management, deployment, and maintaining and monitoring your REST APIs.
