Rest API - HTTP Status Codes

You want to design a REST API endpoint that returns 404 if a user is not found, 401 if the request lacks valid authentication, and 200 with user data if successful. Which status codes should you use for each case?

A500 for missing user, 401 for unauthorized, 200 for success

B401 for missing user, 404 for unauthorized, 200 for success

C200 for missing user, 401 for unauthorized, 404 for success

D404 for missing user, 401 for unauthorized, 200 for success

Step-by-Step Solution

Solution:

Step 1: Match status codes to meanings
404 means resource not found, 401 means unauthorized access, 200 means success.
Step 2: Assign codes to cases
Use 404 if user missing, 401 if authentication fails, 200 if user found.
Final Answer:
404 for missing user, 401 for unauthorized, 200 for success -> Option D
