Is it possible to place a subscription renewal order via API?
Currently there is no way to place a renewal order for non-domain subscription. API method
CreateManualOrder_API can create a renewal order but without any provisioning items,
PlaceOrderAndAuthorize_API can create a renewal order for the domain subscriptions only. There is a feature request with id #PBA-37054 to implement API method to place a renewal order for the hosting subscription.
