Custom stack to MGID
Forward every Custom stack 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.
Connection
Connect Custom stack to MGID with Upstack Data
Custom stack
Not on the list? Send events to Upstack from any stack over webhook or direct post, with the same schema and the same resolution.
Custom stack integration
MGID
Server-side conversions to MGID with hashed identifiers and restored click IDs, so a channel that is hard to attribute stops being invisible.
MGID integrationWhat changes
What changes when Custom stack 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.
Any stack, any framework
Headless, custom checkout, native app or a platform we haven’t listed — if it can make an HTTP request, it can send to Upstack.
The same event schema
Custom events are resolved, filtered and forwarded exactly like a Shopify order.
What actually moves
What Custom stack carries, and what MGID needs.
Custom stack and MGID describe a customer with different vocabularies. This is the mapping Upstack applies on the way through — the left column is what Custom stack can put on an event, the right is what MGID can actually use.
Custom stack sends
- event_name
- whatever you choose to call it
- user identifiers
- any of email, phone, external ID
- value / currency
- if the event carries revenue
- custom properties
- any attribute in your own schema
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.
