# New Balance Invoice

> Sent when money is added to a patient's balance (credit). Same fields as a new invoice; `invoice_line_ids` is always empty.

## When it's sent

* Money is added to a patient's balance (credit) directly.
* A patient pays **more** than what's left on an invoice. The extra amount goes to the patient's balance, and Dentolize sends `NEW_PAYMENT` for the invoice payment, then `NEW_BALANCE_INVOICE` and [`NEW_BALANCE_PAYMENT`](/api-reference/webhooks/new-balance-payment) for the extra.

The request `type` is `NEW_BALANCE_INVOICE`. See the [introduction](/api-reference/introduction) to subscribe to this event and verify the `X-Hub-Signature-256` signature.

<Note>
  The payload has the same fields as [New invoice](/api-reference/webhooks/new-invoice), with an empty `invoice_line_ids` list.
