There are multiple ways to share tracking when you ship an Ordentic order.
You can do it in the portal by opening the order at https://ordentic.com/en/supplier/orders and creating a shipment when you fulfill the order. You can optionally add a tracking URL on that shipment. Tracking is per shipment, so if you ship in parts, each shipment can have its own link. You cannot change a tracking URL after the shipment is saved; create a new shipment if you need a new URL.
When you create the shipment, Ordentic emails the buyer. If you added a tracking URL, that email includes the link, and the buyer can also see tracking on their order page. If you skip the tracking URL, the shipment is still created, but without a track link. Ordentic does not send reminders for missing tracking.
Secondly, you can also create shipments with an optional tracking URL using the Shipments API. Check out our documentation on https://ordentic.com/docs/supplier
