Can anybody explain to me what `balance.available` event in Stripe means. We are receiving this event to our webhook and our application is not configured to handle such event.

I have searched around Stripe documentation but cannot find a clear explanation of what this event is for. Here's an example:

```
{
    "object":
    {
        "object": "balance",
        "available": [
        {
            "currency": "gbp",
            "amount": 1999,
            "source_types":
            {
                "card": 1999
            }
        }],
        "livemode": false,
        "pending": [
        {
            "currency": "gbp",
            "amount": 0,
            "source_types":
            {
                "card": 0
            }
        }]
    },
    "previous_attributes": null
}

```
