# 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 https://moi.matrixorigin.cn/newmoi/workbook/version/save
```

## Preparation before calling

Prepare your personal access token with update permissions, workspace ID, SQL save record ID, and draft version ID to be finalized. `$AI_STUDIO_API_KEY` is the personal access token used as the value of the `X-API-Key` request header; `$WORKSPACE_ID` is the target workspace ID used as the value of the `X-Workspace-ID` request header. You can first [View saved SQL version](list-workbook-versions.md) to 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](list-workbook-versions.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. |
