What does HTTP status code 303 mean?
The 303 See Other status code tells the client that the resource has been created or processed, and the result can be fetched via a GET request at a different URI.
When to use it in APIs
Excellent for POST-redirect-GET patterns. After a client submits a form or resource creation request, return a 303 redirecting them to the newly created resource detail page.
How it compares to other codes
- 302 Found: Used for generic redirects, whereas 303 explicitly forces the client to use a GET request on the target URI.
