Following user requests we have added a new API parameter exclude_addon to the place request.
This only applies to non multi-domain orders.
Behaviour when exclude_addon=0 or is not set.
If your CSR domain does not start with www then the system will automatically create a no cost addon SAN to include the www.
If your CSR domain starts with www then the system will automatically create a no cost addon SAN for the base domain.
Behaviour when exclude_addon=1 is set
The CSR domain will be the only domain included in the order.
