I've been trying to get DHL Parcel UK tracking to work. The link should be:
But gets re-written to:
This has resulted in thousands of customers getting the wrong tracking.
I think the issue is that DHL Parcel UK isn't on the list of tracking companies here https://shopify.dev/docs/admin-api/rest/reference/shipping-and-fulfillment/fulfillment
I guess I have two questions:
1. How can we get DHL Parcel UK supported?
2. Is it really a good idea to re-write tracking URL's? From searching the forum it does seem to cause more problems than it solves as inevitably it is hard for Shopify to keep up with all of the couriers in the world who regularly change their tracking links.
