There are two types of status codes:
1. **[Standard HTTP status codes](#http-status-codes)** 2. **[Application specific codes in the response structure](#application-specific-status-codes)**Typically a non-200 HTTP status code indicates a more severe error condition. Standard meanings of the HTTP codes are used.
401 Unauthorized– Unable to log in. The user cannot be authenticated due to missing or bad authentication (e.g., wrong password).403 Forbidden– The authenticated user is not authorized to perform the command. The user needs specific permission(s). Contact your administrator.
The app specific codes are used to provide a more fine grained status messaging between the client and the backend. These codes are mainly derived from SmartGWT status code structure:
STATUS_FAILURE(-1),
STATUS_LOGIN_INCORRECT(-5),
STATUS_LOGIN_REQUIRED(-7),
STATUS_LOGIN_SUCCESS(-8),
STATUS_MAX_LOGIN_ATTEMPTS_EXCEEDED(-6),
STATUS_SERVER_TIMEOUT(-100),
STATUS_TRANSPORT_ERROR(-90),
STATUS_VALIDATION_ERROR(-4),
STATUS_SUCCESS(0),
STATUS_SYNTAX_FAILURE(100),
STATUS_LICENSE_FAILURE(101),
Obsolete: STATUS_PL_APPROVAL_FAILURE(102),
STATUS_PL_CREATE_FAILURE(103),
STATUS_CALCULATION_FAILURE(104),
STATUS_PA_DATALOAD_ERROR(200),
STATUS_PA_QUERY_ERROR(201),
STATUS_PA_SCHEMA_ERROR(202),
STATUS_PA_ASYNC_CONTINUATION(203);The convention within SGWT is that codes with a number smaller than 0 are failures (although -8 is also a success code). Custom Pricefx codes are introduced too - they start at 100.
