Rest API - Authentication and Authorization

Given this Python code snippet using the requests library, what will be the output if the API key is invalid?

import requests
headers = {"Authorization": "ApiKey wrong_key"}
response = requests.get("https://api.example.com/data", headers=headers)
print(response.status_code)

A200

B500

C404

D401

Step-by-Step Solution

Solution:

Step 1: Understand HTTP status codes for authentication
401 means unauthorized access due to invalid credentials like a wrong API key.
Step 2: Analyze code behavior
The code sends a wrong API key, so the server should respond with 401 Unauthorized.
Final Answer:
401 -> Option D
Quick Check:
Invalid API key response = 401 [OK]

Quick Trick: Invalid API keys usually return 401 Unauthorized status [OK]

Common Mistakes:

Confusing 401 with 404 Not Found
Expecting 200 OK despite invalid key
Thinking server returns 500 error for auth issues
