About Alia
Self-reported attribution then becomes something you can compare against measured attribution, rather than a second unlinked dataset.
Alia runs post-purchase surveys and offers on the confirmation page, capturing attribution and preference data at the one moment a customer is guaranteed to be paying attention.
Its answers are only useful if they attach to a person rather than a session.
Alia presents surveys and offers after checkout and stores responses against the order. Because it operates at the confirmation step, it inherits whatever identity the checkout had, which on a broken session is very little.
What you can do with it
01
Conversions reach Alia through its server-side API with restored click IDs and hashed identifiers attached, so more of what you send is matched on arrival, and the conversions you never saw stop being invisible.
02
Map any order attribute to the conversion Alia receives (profit rather than revenue, new customers rather than repeat buyers, high-value orders rather than every checkout), so the platform learns from the buyers worth acquiring.
03
Responses land against a resolved customer rather than a session, so self-reported attribution can be compared with what actually happened.

All plans. Upstack has three plans that scale with your order volume, and the same integrations are on every plan.
Upstack’s own pixel loads asynchronously and fails silently, so it doesn’t hold up your pages. What each destination adds depends on its Tracking Method. The default, Browser + Server, loads that platform’s own tag on your store, in place of the copy you would otherwise install yourself, and also sends the same events from Upstack’s servers. Choose Server for any destination that offers it and its tag never loads, while its events still arrive from Upstack’s servers.
