How it flows
How a Skio event reaches the Meta Conversions API. Captured on the server, resolved to a person, then sent.
01 Capture
Captured from Skio
Capture Skio subscription events server-side, with the first charge distinguished from every renewal that follows it.

02 Understand
Resolved to one person before it leaves
Every Skio event is matched against a 750M+ device graph, so a phone browse and a desktop checkout resolve to one customer rather than two strangers.

Resolved before it is sent - IdentityMatched against a 750M+ device graph, so a phone browse and a desktop checkout resolve to one customer.
customer_typeNew or returning, resolved before send.- DeduplicationBrowser and server copies of the same purchase collapse on event ID, so nothing is counted twice.
- Bot and fraud filteringAutomated traffic never reaches the model, because what you keep out of the training set matters as much as what goes in.

Forward deduplicated, identity-resolved conversions to Meta through the Conversions API, and give the model a customer instead of a session.

Which events reach the Meta Conversions API
Each Upstack event is mapped to the Meta Conversions API event below before it is sent.
| Upstack event | Sent to Meta Conversions API as | Key data on the event |
| Page view | PageView | URL, referrer, user agent |
| Product view | ViewContent | content_ids, content_type, value, currency |
| Add to cart | AddToCart | content_ids, value, currency |
| Checkout | InitiateCheckout | value, currency, num_items |
| Purchase | Purchase | value, currency, order_id, content_ids |
Every event carries every available match key: em, ph, fn, ln, ct, st, zp and country, plus fbc, fbp and external_id. Personal data is hashed with SHA-256 before it leaves Upstack.
The catch
A first charge is an acquisition and a renewal is not, but both arrive as purchases.
Sending renewals as conversions is the single most common way a subscription brand teaches Meta to re-buy its existing subscribers.
Where to check in the Meta Conversions APIDelivery you can audit
Events Manager › your dataset › Event Match Quality
Server events appear with a Server badge, and Event Match Quality is scored per event type.
What changes
What changes when Skio feeds the Meta Conversions API. Two gains on the Meta Conversions API side, two on the Skio side.
Meta Conversions API
Higher Event Match Quality
More hashed identifiers on every event (email, phone, external ID, click ID), so EMQ rises and Meta matches more of what you send.
Meta Conversions API
Pixel and CAPI, one install
One source of truth for both, with browser and server events deduplicated on event_id so purchases are never double-counted.
Skio
Every event, server-side
Storefront and checkout events are captured from Skio on the server, independent of the browser.
Skio
One setup, every destination
Connect Skio once and forward to every ad platform, email tool and warehouse you run.
-
01
Connect Skio
Capture Skio subscription events server-side, with the first charge distinguished from every renewal that follows it.
-
02
Add the Meta destination
Under Destinations, add Facebook Advertising with your Pixel ID (a 15 or 16 digit number) and a Conversions API token generated in Events Manager, which starts with EAA.
-
03
Check Event Match Quality
Upstack marks the destination Healthy, and Events Manager lists the server events with a Server badge. Open your dataset’s Event Match Quality: it is scored per event type, and Meta takes 24 to 48 hours to score new events.
FAQ
Questions about Skio and the Meta Conversions API.
What is Event Match Quality (EMQ) and why does it matter?
EMQ is Meta’s score, from 0 to 10, for how reliably it can match a conversion event back to a Meta user. Higher EMQ gives Meta’s algorithm more signal to optimize against, and server-side delivery through CAPI typically raises it because events carry more match keys and are not blocked by browser restrictions.
Will purchases be counted twice with the Pixel and the Conversions API both running?
No. Upstack sends a shared event_id on every server-side event, and Meta deduplicates against the matching browser Pixel event. As long as the Pixel ID in Upstack matches the Pixel ID firing in your storefront, deduplication is automatic.
Which events does the Meta Conversions API receive?
PageView, ViewContent, AddToCart, InitiateCheckout and Purchase, each mapped to the Meta Conversions API event of the same name.
Which customer parameters are sent to the Meta Conversions API?
Every event carries every available match key: em, ph, fn, ln, ct, st, zp and country, plus fbc, fbp and external_id. Personal data is hashed with SHA-256 before it leaves Upstack.
How do I check that Skio events are reaching the Meta Conversions API?
Upstack marks the destination Healthy, and Events Manager lists the server events with a Server badge. Open your dataset’s Event Match Quality: it is scored per event type, and Meta takes 24 to 48 hours to score new events.
How long does it take to connect Skio to the Meta Conversions API?
Most brands are live in under 20 minutes. Once Skio is connected, every destination receives the same resolved events, the Meta Conversions API included.
