@bc-traciporter This is the first time I have come across the Aftership terminology.
I didn't realise the /v2/orders/shipments called the shipping service like this 😮

@bigcommerce/team-shipping can you please review this PR for us.

Yeah Aftership is our backup tracking link for when a provider has not been setup in shipping provider or is not one of our natively integrated providers.
Also to note that if it is not in the list of External providers they will not get an aftership link either.
