Glossary: GraphQL APIs

HTTP status codes

Also written: 200, 401, 403, 404, 406, status code

Numbers in an HTTP reply saying how it went. GraphQL replies are usually 200 OK even when they hold errors; REST uses 404 (not found) and 401 (not logged in), 403 means forbidden, and 406 Not Acceptable is what the browser gets when GraphiQL is off.
