BigCommerce to MGID

Forward every BigCommerce event to MGID server-side, resolved to a person against a 750M+ device graph — with restored click IDs, deduplicated conversions and delivery you can audit.

What changes

What changes when BigCommerce feeds MGID.

Server-side delivery

Events reach MGID through its server API, not the browser — so ad blockers, ITP and consent banners don’t cost you conversions.

Identity-resolved events

Every event sent to MGID carries a resolved customer, matched against a 750M+ device graph.

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 MGID needs.

BigCommerce and MGID 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 MGID 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

MGID receives

hashed email / phone
identity matching on arrival
mgid_click_id
credit the click that drove it
external_id
stable person across sessions
event_id
dedupe against the browser pixel
value / currency
value-based bidding

Delivery you can audit

How you know it is working.

Ad platforms accept almost anything and tell you very little. These controls exist so you can see what was sent and what was accepted, rather than inferring it from a reporting gap.

  • Per-event inspection

    Every conversion is inspectable from the moment it fires to the moment the platform confirms it.
  • Deduplication

    Browser and server copies of the same purchase collapse on event ID, so nothing is counted twice.
  • Bot and fraud filtering

    Automated traffic never reaches the model, because what you keep out of the training set matters as much as what goes in.

Where to check in MGID

MGIDDashboardConversions. The postback log records each server-side conversion and the click it was matched to.
