What ever happened to the Tax Services API? I remember seeing documention in the API docs but all traces seems to have been wiped from the face of the earth, there are only a handful of references around the net now.
Does anyone have a link to the documentation? has the API been closed off to developers?
Looks like they have decided to hide it behind closed doors for the few privileged ones entitled to challenge Avalara's integration with Shopify.
Excuse the sarcasm ;-)
Quite possible there were technical reason why to do this - real-time tax calculations are quite taxing. Also leaving this to users is like opening pandora's box for support engineers.
