FAQ
What are HTTP status codes?
HTTP status codes are three-digit numbers returned by a server in response to a client request. They indicate whether the request was successful, redirected, or resulted in an error.
What is the difference between 401 and 403?
401 Unauthorized means the client has not authenticated (needs to log in). 403 Forbidden means the client is authenticated but does not have permission to access the resource.
What does 418 I'm a Teapot mean?
Status code 418 was defined in RFC 2324 as an April Fools' joke. It indicates that the server refuses to brew coffee because it is a teapot. Some APIs use it humorously.
When should I use 404 vs 410?
Use 404 when a resource is not found and may appear later. Use 410 when a resource has been permanently removed and will not return.
