including Basic Authentication to an API request code example

Example 1: api authentication work in your project

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: basic authentication in REST api Dajngo

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework.authentication.BasicAuthentication',
        'rest_framework.authentication.SessionAuthentication',
    ]
}
