# Error handling

The Attuitive API uses standard [HTTP response codes](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Status) to indicate the result of a request. It can be assumed anything in the `2xx` range was successful. Codes in the `4xx` range indicate a client error, and something that can be fixed by correcting information in the request (e.g. a bad ID or missing parameters) and trying again. Codes in the `5xx` range should be rare and indicate an error from Attuitive.

**All** responses outside of the `2xx` range will return a standard error format:

```json
{
  "status": 400,
  "message": "Invalid identifiers",
  "moreInfo": "The provided identifiers should be a valid JSON object."
}
```
