What does it mean to know REST API?

Question

RESTful API

Greetings) In vacancies on the frontend they write everywhere (knowledge of the REST API). What does it mean to know him? What kind of questions should I know the answer to?

Answer 1

In terms of theory, it’s enough to understand everything that is at the link
https://restfulapi.net/
And if you also understand the Richardson Maturity Model, then most likely even the person conducting it will start to swim at the interview :)
They usually ask about HTTP methods, formation rules URL for interacting with resources, versioning and response codes. In any case, the link is there.
On the frontend, they may still ask about the libraries that I used to make requests, the method of storing the authorization token, and some other specifics

Answer 2

As such, there is no REST API. There is REST architectural style, and there is RESTful Services.
(I don't know how, and I've never liked jobs that were written by someone who doesn't know who.)

TL;DR: REST only defines the communication format. And if the service follows this format, then it can be called RESTful.

Answer 3

POSTMAN you will say that you are rummaging
well and rummaging
how are you going to use AJAX and newfangled APP frameworks without REST?

Answer 4

This means not only being able to make requests, but also being able to design it (REST).
Let's say there is a product entity; GET /product/{id}
In the REST paradigm, how to get products with id 1, 2, 3 in one request?
