# Error Codes

When encountered by an expected error, Groups API returns an object like so:

```json
{
    "code": 40,
    "details": "Attendee not found."
}
```

In this object:

* code: Field that will be explored in this page, it parameterizes errors so they can be easily managed by Groups and other integrations.
* details: Field that contains the error message.

{% hint style="info" %}
Groups supports details being displayed in Turkish and English. 
{% endhint %}
