[Does a Fulfillment support one more multiple tracking numbers?

The 2020-01 Fulfillment API documentation says that each fulfillment only supports a single tracking number:

 

Each fulfillment supports a single tracking number. If you need to use multiple tracking numbers, then you should create separate fulfillments.

Listed in fulfillment properties is the `tracking_numbers` property which is clearly an array. The description suggests that multiple tracking numbers are supported in a single fulfillment instance:

Which is correct?

 

Some clarity and an update to the documentation would be great.

 

Thank you!

Came here to post the same thing. It seems to be the case for both `tracking_numbers` and, correspondingly, `tracking_urls`.

Even more confusing - the GraphQL Fulfillment object contains a `tracking_info` field that uses the singular `number` and `url`:
https://shopify.dev/docs/admin-api/graphql/reference/object/fulfillment/fulfillmenttrackinginfo?api[...

I haven't tested this recently, but I believe I've been able to add multiple tracking numbers and URLs to a single fulfillment via the REST API.

So, are the singular properties merely a recommendation at this point? If so, the GraphQL values must be simply grabbing the first item from a list and crossing fingers there aren't any more?

Would love some clarification on this as well.
