Question
We have issue integrating API, we update invoice with new CustomerRef over API, it also updates billing address even we do not send it. If we send address, it is ignored.
We have existing proforma/invoice and in a time, we need to change CustomerRef to another one over API. When we do this, it works, but it also changes Billing address to the new CustomerRef address. We want to keep the original record. Unfortunatelly, even when we specify this, we are not able to avoid the change of address, any idea please?
