Do you know about REST API's ?
Topics Covered π
-> What is REST?
-> REST API ?
-> REST endpoint ?
-> API Gateway ?
What is REST?
REST stands for Representational State Transfer. Itβs a way for computer systems to communicate over the internet. Imagine you want to access a book in a library. You donβt take the whole library home; instead, you just take the book you want and read it. REST works in a similar way, allowing you to access specific pieces of data on a server without needing to get all the data stored there.
What is REST API ?
So, a REST API is like a menu in a restaurant (API) that allows you to place an order (make a request) asking for a specific dish (a resource) to be prepared, and then served to you (get the response).
REST endpoint ?
An API/REST/Backend endpoint means the URL of the service that the client could hit. For instance, myservice.com/users/{username} is a backend endpoint for fetching the user details of a particular user from the service. The REST-based service will expose this URL to all its clients to fetch the user details using the above stated URL.
API Gateway ?
An API Gateway is a server that acts as an API front-end, receiving API requests, enforcing throttling and security policies, passing requests to the back-end service, and then passing the response back to the requester. In essence, it acts as a reverse proxy to accept all application programming interface (API) calls, aggregate the various services required to fulfil them, and return the appropriate result.
