The tracking numbers of the fulfillment, one or many.
With multiple tracking numbers, you can provide tracking information for all shipments associated with the fulfillment, if there are more than one. For example, if you’re shipping assembly parts of one furniture item in several boxes.
Tracking numbers will be clickable in the interface if one of the following applies (the highest in the list has the highest priority):
* Tracking URLs provided in the urls field. The tracking URLs will be matched to the tracking numbers based on their positions in the arrays. * [Shopify-known tracking company name](https://shopify.dev/api/admin-graphql/latest/objects/FulfillmentTrackingInfo#supported-tracking-companies) specified in the company field. Shopify will build tracking URLs automatically for all tracking numbers specified. The same tracking company will be applied to all tracking numbers. * Tracking numbers have a Shopify-known format. Shopify will guess tracking providers and build tracking URLs based on the tracking number formats. Not all tracking carriers are supported, and multiple tracking carriers may use similarly formatted tracking numbers. This can result in an invalid tracking URL. It is highly recommended that you send the tracking company and the tracking URLs.
