BigCommerce to Klaviyo

Forward every BigCommerce event to Klaviyo server-side, resolved to a person against a 750M+ device graph — so flows trigger on a known profile rather than an anonymous session.

What changes

What changes when BigCommerce feeds Klaviyo.

Recover carts you couldn’t email

Anonymous browsers are resolved to a known profile, so abandonment flows can trigger for visitors Klaviyo never identified.

Profiles, not sessions

Events arrive attached to a resolved customer, so flow logic and segmentation work on a person.

Every event, server-side

Storefront and checkout events are captured from BigCommerce on the server, independent of the browser.

One setup, every destination

Connect BigCommerce once and forward to every ad platform, email tool and warehouse you run.

What actually moves

What BigCommerce carries, and what Klaviyo needs.

BigCommerce and Klaviyo describe a customer with different vocabularies. This is the mapping Upstack applies on the way through — the left column is what BigCommerce can put on an event, the right is what Klaviyo can actually use.

BigCommerce sends

order_id
BigCommerce order
email / phone
checkout contact
customer_id
BigCommerce customer record
products
catalogue items on the order
total_inc_tax
order value

Klaviyo receives

email / phone
the profile key — no profile, no send
external_id
tie a browse to a known person
$value
flow and campaign revenue attribution
event properties
what the flow branches on

Sending you can audit

How you know it is working.

Messaging mistakes are expensive and public. These controls exist so a flow never fires against a profile that should not have received it.

  • Per-profile inspection

    Trace any event to the profile it resolved to, and see why.
  • Deduplication

    One order produces one event, so a single purchase cannot trigger the same flow twice.
  • Bot and fraud filtering

    Automated traffic never becomes a profile, so list quality and deliverability are not paying for it.

Where to check in Klaviyo

KlaviyoAnalyticsMetrics. The event appears as its own metric, and the profile count on it is the number you were losing before.
