Short answer: Only when you’re using automatic integrations. This is not possible with the webshop, but it is in the API.
It’s possible to add thank you notes, custom products or packaging to your orders when you’re using our API. This applies to:
When using one of these options, you can send us some items. We will add these to our warehouse and give you an article number. This article number can be used to place orders for this item. The items are partner-owned in our system, that means you are the only one who can see them in the product list. Other Invition partners can’t see your products. Please note that a storage fee is calculated weekly for stored products so make sure to sell the products you store in our warehouse. Contact our support desk for more information.
