# Restore previous version

> Roll an automation back to its previous published version

This endpoint rolls an automation back to the version published immediately before the current one and re-publishes it — the undo for an update that made things worse. Only the previous version is supported. An automation that was turned off stays off after the restore.

### Path Parameters

<ParamField path="id" type="string" required>
  The ID of the automation (from [List automations](/api-reference/automations/list-automations))
</ParamField>

This endpoint takes no request body.

### Response

<ResponseField name="automation_id" type="string">
  The automation's ID
</ResponseField>

<ResponseField name="name" type="string">
  The automation's name after the restore
</ResponseField>

<ResponseField name="status" type="string">
  `enabled` or `disabled` — the on/off state the automation had going into the restore is preserved
</ResponseField>

<ResponseField name="restored_version_id" type="string">
  The ID of the version that is now live
</ResponseField>

<ResponseField name="note" type="string">
  Confirmation that the previous version was restored and re-published
</ResponseField>

A missing automation — or one that does not belong to your account — returns a `404`.

### Error codes (`422`)

| `error`               | Meaning                                                                                                                            |
| --------------------- | ---------------------------------------------------------------------------------------------------------------------------------- |
| `no_previous_version` | There is no earlier version of this automation to roll back to.                                                                    |
| `rollback_failed`     | The previous version could not be restored — nothing changed.                                                                      |
| `publish_failed`      | The previous version was restored as the draft but could not be published, so it is not live yet — publish it in the app or retry. |
