Create a new draft order in IABAKO.

After this operation, you will be able to validate (confirm) the order,
generate the associated invoice and handle installments and payments.

Some considerations:

• Only lines attribute is mandatory.
• If number is not provided, it will be auto-generated.
• If externalId is not provided, it will be auto-generated.
• Customer can be assigned by externalId or number (if already exists in IABAKO). Otherwise a new Customer will be created.
• Customer fields (of an existing customer) will be updated (except if synchronisation is disabled for this customer).
• Products in lines attributes can be assigned by externalId or number (if already exist in IABAKO). Otherwise a new Product will be created.
• Product fields (of existing product) will be updated (except if synchronisation is disabled for this product).
