Common HTTP Response Codes
A subset of HTTP response codes for quick reference. Other codes exist but are either typically handled by the server, web framework, or they're rarely, if ever, used by me.
| Status | Phrase | Usage | Response body | Response headers |
|---|---|---|---|---|
| 200 | OK | Success | Any requested content or applicable information | |
| 201 | Created | Success and I created a new resource | Usually the newly created resource | |
| 202 | Accepted | I accepted the request but will process it asynchronously | Either empty or some information regarding the upcoming processing | |
| 204 | No Content | I have no content to return, maybe the headers are useful | ||
| 303 | See other | Your PUT or POST was successful and now redirecting you to GET the resource via another URL | URL | |
| 307 | Temporary Redirect | Redirecting you temporarily to another URL but send future requests here | URL | |
| 308 | Permanent Redirect | Redirecting you permanently to another URL so send all future requests there | URL | |
| 400 | Bad Request | You sent a request containing errors. Fix them and try again! | Error page or parsable details | |
| 401 | Unauthorised | I don't know who you are and the resource is restricted | Error page or parsable details | |
| 403 | Forbidden | I know who you are but you don't have access rights | Error page or parsable details | |
| 404 | Not Found | I can't find the resource OR I'm secretly hiding a restricted resource from you (401 or 403) | Error page or parsable details | |
| 405 | Method Not Allowed | You can't perform that action on this resource | Error page or parsable details | Allow: comma separated list of allowed methods |
| 410 | Gone | Resource permanently removed | Error page or parsable details | |
| 411 | Length Required | Content-Length header is missing and required, probably because I have a request body limit and only want to read the required number of bytes | Error page or parsable details | |
