HTTP 207 Multi-Status vs 428 Precondition Required
HTTP 207 (Multi-Status) is a 2xx Success response, while 428 (Precondition Required) is a 4xx Client Error response. 207 indicates that the response body contains status information for multiple resources, in situations where multiple status codes might be appropriate (WebDAV). In contrast, 428 means that the server requires the request to be conditional (e.g., include If-Match header) to prevent lost updates.
