Loop Subscriptions to PostHog

Forward every Loop Subscriptions event to PostHog server-side, resolved to a person against a 750M+ device graph — so records and reporting reflect the person, not the device.

What changes

What changes when Loop Subscriptions feeds PostHog.

Server-side delivery

Events reach PostHog 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 PostHog carries a resolved customer, matched against a 750M+ device graph.

Every event, server-side

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

One setup, every destination

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

What actually moves

What Loop Subscriptions carries, and what PostHog needs.

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

Loop Subscriptions sends

subscription_id
the Loop subscription across its whole life
email / phone
subscriber contact
event_type
renewal, swap, skip, pause, cancel or save
line_items
products after any swap
total / interval
charge amount and billing cadence
customer_type
new or returning, resolved before send

PostHog receives

distinct_id
the person, across devices
event name and properties
funnels and retention
$set person properties
user-level attributes

Records you can audit

How you know it is working.

A CRM is only as trustworthy as its worst duplicate. These controls exist so the record reflects the person.

  • Per-record inspection

    Trace any property back to the event that set it.
  • Deduplication

    One person, one record, across devices and identifiers.
  • Bot and fraud filtering

    Automated traffic never becomes a contact.

Where to check in PostHog

PostHogActivity, then check that a single person shows events from more than one device.
