3. What is restfulAPI?
● REST - Representational State Transfer
● REST is an architecture style for designing networked applications.
● In many ways, the World Wide Web itself, based on HTTP, can be viewed as a REST-
based architecture.
● RESTful API uses versioning. e.g POST /V1/todos/
● RESTful API explicitly take advantage of HTTP methodologies defined by the RFC 2616
protocol. They simply use "PUT" to change the state of or update a resource, which can be
an object, file or block; "GET" to retrieve a resource; POST" to create that resource; and
"DELETE" to remove it.
● Restful API uses HTTP Headers add information about the request and the response.
● Restful API uses HTTP Status Codes Correctly.
● Restful API is stateless.
● Restful API commonly use JSON or XML as a form of response.
● Each API request returns a subsequent API response.

4. What is restfulAPI?
● REST - Representational State Transfer
● REST is an architecture style for designing networked applications.
● In many ways, the World Wide Web itself, based on HTTP, can be
viewed as a REST-based architecture.
● RESTful API uses HTTP for all four CRUD
(Create/Read/Update/Delete) operations.
● Each request returns a subsequent response.
● HTTP Verbs – POST, GET, UPDATE, PUT, PATCH, DELETE
● HTTP Headers – Content-Type, Content-Length etc.
● Commonly used by Mobile Applications and Single Paged Apps.
● Commonly use JSON or XML as a form of response.

5. A stateless protocol does not require the server to retain information or
status about each user for the duration of multiple requests.

6. Requests are made up of a verb (POST, in this example), headers that describe the
message, and a body (Hello World, in this example).
The request is a message that describes what you want the server to accomplish.
Likewise, the response consists of three pieces: a status code (200), headers
describing the response and the body itself.
HTTP Verbs describe the type of operation:
GET: Retrieve a resource
POST: Create a resource
PUT: Update a resource
DELETE: Delete a resource
On the Web, the most common verb is GET. This is because the main purpose of a
Web page's function is to request different resources that make up a page. In REST-
based APIs, we leverage these verbs to describe the types of operations we want.

8. How about the security?
● REST api can be exposed to the public. They usually call it as Public APIs
● You can use OAUTH, HTTP Basic or JWT.
● OAuth is an open standard for authorization, commonly used as a way for Internet
users to log in to third party websites using their Google, Facebook, Microsoft,
Twitter, One Network, etc. accounts without exposing their password.
● HTTP Basic - In the context of an HTTP transaction basic access authentication is a
method for an HTTP user agent to provide a user name and password when making
a request.
● JSON Web Tokens are an open, industry standard RFC 7519 method for
representing claims securely between two parties.
