# Errors

ITCare API uses conventional HTTP response codes to indicate the success or failure of an API request.

As a general rule:

* Codes in the **`2xx`** range indicate success.
* Codes in the **`4xx`** range indicate incorrect or incomplete parameters (e.g. a required parameter was omitted, or an operation failed with a 3rd party, etc.).
* Codes in the **`5xx`** range indicate an error with ITCare's servers.

ITCare also outputs an error message and an error code formatted in JSON:

```json

{
    "status": "BAD_REQUEST",
    "errorCode": "INVALID_FIELD_VALUE",
    "errorDesc": "name",
    "errorMessage": "Error on field 'name'
}


```
