I almost always use the Dutch carrier PostNL to ship the goods. when I generate and print a shipping label via the Sendcloud app, then the orders are automatically fullfilled and the customer is being sent the track and trace number together with the international tracking website (https://www.internationalparceltracking.com/), which is in English. That is great, most of my customers are international.
However, if I manually make a shipping label then I have of course to fullfill the orders manually too. I then input the track and trace number, choose 'PostNL' from the dropdown carrier list and send the customer the shipping notification. But the customer gets the tracking link to the portal page of the Dutch PostNL website (www.postnl.nl) instead of the (international) tracking website. That's not good.
How can I change the carrier's tracking website link for manually generated shipping notifications?
