Cost centers

If you want to apply cost centers, you can do so by using the billingId. You can provide a billingId for each individual order.

For example, if you have a campaign named "Christmas 2024" and you want all costs for this campaign to be separately specified on your invoice, then provide "Christmas 2024" as the billingId for those orders.

Please see this JSON example on how to apply the billingId.

P.S. Do not use the billingId for unique IDs.
