HTTP 201 Created

Success code, RFC 9110, section 15.3.2

What it means

The request created something new. The Location header points to the new resource, or if it is missing, the address you posted to is the new thing.

A real response

This is the request and the answer our test server gave when we asked it to return 201.

GET /c/201 HTTP/1.1
Host: example.com

HTTP/1.1 201 Created
Date: Sat, 14 Nov 2026 10:00:00 GMT
Content-Type: text/html; charset=utf-8
Location: /items/42
Content-Length: 11

If you run the site

Use 201 after a POST (or PUT) that creates a record. Send a Location header with the address of the new item, and the new item in the body if it is small. Use 200 when you only updated something that already existed.

If you are a visitor

Nothing to fix. It tells your program that the item now exists.

A common mistake

Forgetting the Location header, so the client has to guess where the new item lives.
