What is an HTTP Status Code?
An HTTP status code is a three-digit number a server returns with every response, telling the client whether the request succeeded, needs a redirect, or failed — and why. The first digit indicates the general category.

Frequently Asked Questions
What do the different status code ranges mean?
1xx is informational, 2xx means success, 3xx means redirection, 4xx means the client made an error, and 5xx means the server encountered an error.
What's the difference between 401 and 403?
401 Unauthorized means you haven't authenticated (or your credentials are invalid). 403 Forbidden means you're authenticated but not allowed to access the resource.
