## Status Codes

p
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)**

## HTTP 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.


## Application Specific Status Codes

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.
