# Error handling

> How Imprint communicates errors

Imprint uses standard HTTP codes to indicate the success or failure of a request. In general, codes in the **`2xx`** range indicate success, and codes in the **`4xx`** range indicate an error. When an API call fails, Imprint will also provide an error object in the response body, which includes an error code (**`type`**), the human-readable error description (**`message`**), and (if applicable) the parameter related to the error (**`param`**).

```json 400 theme={null}
{
  "error": {
    "type": "INVALID_REQUEST_ERROR",
    "message": "Invalid email format",
    "param": "email"
  }
}
```
