For some time now we noticed that the names of shipping tracking company names in the docs don’t match with the names used in the API.
There doesn’t seem to be any singular resource that has the correct strings documented. The only way to figure them out is to set one tracking company in the Shopify Admin we interface and then read the string for it in the API. Very manual.
It would be great if the docs would document the exact tracking company name strings.
In a few places questions are answered with linking to the docs, like here Carrier Mapping for Shopify - #2 by Ben-Shopify
But that doesn’t really answer the questions, because of the mismatch.
