# Finalize SQL version

Save and finalize a draft version. After finalization this version is read-only and the SQL text cannot be updated.

```text
POST $CLOUDSIGMA_API_BASE/workbook/version/save
```

## Before you call this API

Configure the [regional API endpoint and authentication](https://omnifabric.cloudsigma.com/docs/developer/endpoints-and-authentication.html.md), and select the target workspace.

First [list saved SQL versions](https://omnifabric.cloudsigma.com/docs/reference/api/ai-studio/data-processing/sql-workbooks/list-workbook-versions.html.md) and confirm the version status.

`$WORKBOOK_ID` in the example below is the ID of the SQL saved record and `$VERSION_ID` is the version ID with status `draft`. If you need to modify the finalized SQL, create a new draft version.

## Request body

Replace caller-specific values in the example with actual values.

## Successful response

`data` is empty on success. You can then [View the version of the saved SQL](https://omnifabric.cloudsigma.com/docs/reference/api/ai-studio/data-processing/sql-workbooks/list-workbook-versions.html.md) to confirm that this version of `status` is `finalize`.

```json
{
  "code": 200,
  "data": null
}
```

The response fields are as follows.

| Field | Type | Description |
| --- | --- | --- |
| `data` | null | Fixed to `null` when finalized successfully. |
