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 your own products to your orders when you’re using our API. This applies to:
When using one of these options, you can send us some products like a screen protector, charging cable or whatever you like to ship with the orders. We will add these to our warehouse and give you an article number. This article number can be used to place orders for this product. The products 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 have enough sales to cover the storage fee. Contact our support desk for more information.
