api authentication and authorization code example

Example 1: api authentication

I use bearer tokens in my current framework.
I send a get request to special API endpoint by providing valid 
credentials, then it will return Access Token. I use that token 
in my request header and access other API endpoints

Example 2: authorization type in api

Authorization :
It's a process of granting or denying access to resources.
Mostly it happens after Authentatication.

Most of the projects I worked on use Bearer token
with JWT in Authorizaiton header.
I have endpoint that I can use to generate this token
and pass it to the each requests in my test.

Different ways to making authorized request:
1- Basic Auth
       (providing username and password along with each request)
2- Api Keys
       (It is provided token by the api vendor and
        it could be as query parameter or header
3- Bearer Token
       (We can get it by requesting to certain endpoint)
       Most known jwt(json web token)
4- Auth2
      (A much more secure way of authorizing your request
      The flow is similar to Login with facabook,google
       Eventually the token still get added to the 
       Authorization header)
