In general, Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, lighthouse test failed, etc.). Codes in the 5xx range indicate an error with Hansei servers (these are rare).

List of common errors codes:

HTTP Status Description
