I would like to suggest adding the Branded Tracking page URI via an API call. We love the branded tracking page, but as of now, our customers can only get to it via the shipping confirmation email. We'd like to integrate the page into our store customer experience, but it is impossible as of now to bring the url into our customer account page.
To that end, it would be even better if the Magento 2.3 Shipstation extension pushed the information back to the order shipment, so that we could forego any custom coding!
