Slovakia is configured with automatic acknowledgement, so retrieving a notification marks it as read. Manual acknowledgement applies only if you change your ERP System ID configuration.

Because autoAcknowledgement is configured as true for Slovakia, your system doesn't need to send a separate acknowledgement after retrieving notifications. Notifications are automatically marked as read when your GET request returns them.

If you switch your ERP System ID configuration to manual acknowledgement, you'd need to send a PUT request after processing each notification. For the full acknowledgement request structure, see Check notifications.
