Rest API - Authentication and Authorization

You wrote this code to send a Bearer token but the server always responds with 401 Unauthorized. What is the likely error?

headers = {"Authorization": "bearer mytoken123"}
response = requests.get(url, headers=headers)

AThe URL is incorrect

BThe token string is missing

CThe header name should be 'Token' instead of 'Authorization'

DThe word 'bearer' should be capitalized as 'Bearer'

Step-by-Step Solution

Solution:

Step 1: Check Bearer token header case sensitivity
The 'Bearer' keyword in the Authorization header is case sensitive and must be capitalized.
Step 2: Identify the error in the code
The code uses 'bearer' in lowercase, causing the server to reject the token and respond 401.
Final Answer:
The word 'bearer' should be capitalized as 'Bearer' -> Option D
Quick Check:
Bearer keyword is case sensitive [OK]

Quick Trick: Capitalize 'Bearer' exactly in Authorization header [OK]
