What is the significance of HTTP status codes starting with 200?

HTTP status codes starting with 200 indicate successful request execution. They inform the client that the server has successfully processed the request and returned the expected result.

Main codes in this group:

• 200 OK — the request was successful, and the response contains the requested data.
• 201 Created — the request was successful, and a new resource has been created as a result.
• 202 Accepted — the request has been accepted for processing but is not yet completed.
• 204 No Content — the request was successful, but there is no response body.

Example in Python using the requests library:

import requests

response = requests.get('https://example.com')
if response.status_code == 200:
    print('Request successful')
