Part of Ingrid Promise (Delivery Checkout)
Ingrid splits A/B test traffic by checkout session, not by person.
Each session gets a variant when it starts, and keeps it for the whole session.
Sessions are split evenly between the Original and the variant(s).
The same shopper can see a different variant in a new session, for example on another device.
For most merchants, a session starts when the shopper reaches the checkout page. Depending on your integration, it can start earlier, for example when they add something to the cart.
