The Decionis extension hooks Adobe Commerce's checkout webhook synchronously: an order that breaks your margin floor is halted at the point of placement, and anything the engine can't evaluate is let through rather than blocked. It has passed Adobe's technical review on Magento 2.4.9 and is awaiting marketplace release.
A stacked promotion or drifted price that puts the order under your floor is halted synchronously, before it is placed.
Cart price rules that overlap in ways nobody intended — checked against your policy on every order.
Pricing that diverges across store views and websites, evaluated against one shared floor.
Margin clears your floor — the order is placed untouched.
The order breaks your floor — halted at the checkout webhook before placement.
If the engine can't answer, the order proceeds. A checkout outage is never Decionis's doing.
