Create Fulfillment API: Tracking Number not getting linked to the provided URL for Other Company

[OrderCup1]

Hi,

We are facing a strange issue where the tracking number sometimes doesn't get linked to the provided tracking URL for Other company in the Create Fulfillment API call.

The same request for some other order works just fine. The tracking number does get updated everytime and we always get back a success response from Shopify, however the URL doesn't get linked to the tracking number every-time.

What could be causing this? Are there any cases where Shopify will not link the tracking number even when the URL is provided and company is Other?

Note that our API request body structure is correct as is evident from the success response we get.

Regards,

Nilesh
