description: topi is a European hardware-as-a-service (HaaS) fintech that lets B2B sellers and retailers offer tech devices,
  IT hardware, and equipment as flexible monthly rental subscriptions instead of one-off purchases, across eCommerce, telesales,
  and point-of-sale channels. Merchants embed topi rentals into their checkout through the OAuth2-secured topi Seller API
  (catalog, offers, orders, shipments, and shipping methods) and the topi Elements embeddable web components, with a dedicated
  sandbox for end-to-end testing. Backed by Creandum.

  description: '#### Assets without serial numbers


    Some assets might not have a serial number (e.g. accessories). In order to send them with the shipment, explicitly pass
    an empty string `""` as the `serial_number` for this asset.


    > Note, that every asset, that has a **rent option**, requires a serial number even if it has been directly purchased.
    The request will fail with an according message if such a serial number is missing.


    > Also note, that every item of an order has to be shipped for the order to be completed. This can be done in multiple
    shipments.'
