The normal order API doesn't decrement stock levels as noted in this question in 2016 and confirmed again by my question in December 2020.
I've just noticed the Create Atomic Order API that seems to have popped up in February '21 which looks great. https://docs.clover.com/reference#ordercreateatomicorder
I cannot see from the documentation though - does the Create Atomic Order API automatically decrement stock levels?
Thanks!
