428 Precondition Required
Description
The HTTP 428 Precondition Required response status code indicates that the server requires the request to be conditional.
Typically, this means that a required precondition header, such as If-Match, is missing.
When a precondition header is not matching the server side state, the response should be 412 Precondition Failed.
