6. Select **Save**.

9. Confirm that the custom API host appears under the device ID. The API host is shown only when **Custom Host** is used.

## Notes

* Enter the domain only, for example `api.example.com`. Do not enter `https://`, a port, a path, a query, or a fragment. The app uses HTTPS automatically.

## Frequently Asked Questions

### Q: When would I need to change the API host?

**A:** Only for Private Cloud deployments where EventX is hosted on a custom domain. Standard EventX customers should not need this and can skip it entirely.

### Q: What version of the Check-in App is required?

**A:** Version 6.2.1 or later. If you don't see the "Change Host" button, update the app from the App Store.
