| Field            | Type             | Required | Default | Description                                                                                                                                                                                                                                                                                                                  |
| ---------------- | ---------------- | -------- | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `invoiceId`      | `string`         | Yes      | —       | The ID of the invoice to publish.                                                                                                                                                                                                                                                                                            |
| `version`        | `number`         | Yes      | —       | The version of the invoice to publish. This must match the current version of the invoice; otherwise, the request is rejected.                                                                                                                                                                                               |
| `idempotencyKey` | `string \| null` | No       | —       | A unique string that identifies the `PublishInvoice` request. If you do not provide `idempotency_key` (or provide an empty string as the value), the endpoint treats each request as independent. For more information, see [Idempotency](https://developer.squareup.com/docs/build-basics/common-api-patterns/idempotency). |

Use the official [PublishInvoice reference](https://developer.squareup.com/reference/square/invoices-api/publish-invoice) for provider field semantics and limits.

## Output

Returns the official `Square.PublishInvoiceResponse` response as a codec-safe object. Square integer money amounts remain `bigint` values.
