# Approve or roll back a safe update

POST https://api.modulards.com/api/public/v1/site-actions/{siteAction}/validate
Content-Type: application/json

Gives your verdict on a safe update that is waiting for your decision (`status` `requires_action`): approve it to keep the update, or roll it back to restore the website as it was. A safe update that nobody decides within 7 days of starting to wait is approved automatically. Returns the site action after the decision, with its details.

**Body**
- `action` (`approve` or `rollback`, required): your verdict.

**Errors**
- **404**: the site action does not exist, is not one of your organization's, or is not waiting for a decision.
- **422**: `action` is missing or is not `approve` or `rollback`.
