FB CAPI
CAPI (Conversions API) is server-side sending of events back to the ad platform. When a registration or deposit happens on your side, Qubix sends that event to Facebook's server so that its algorithms optimize ad delivery more accurately. Unlike the browser pixel, server-side sending is more reliable: events are not lost because of blockers and browser restrictions.
Why this is needed
- The platform receives data about real conversions even when the browser pixel didn't fire.
- Campaign optimization is driven by actual registrations and deposits — the advertising learns from the right events.
- Less discrepancy between platform data and the tracker — see Δ Reconcile.
This is not a separate screen
Server-side sending has no page of its own in the admin — it works in the background. You only notice it if something goes wrong.
note
If an event fails to send to the platform, an alert arrives in Telegram — the Conversion send failures role (events: regs and deps that failed to be delivered to Facebook).
Where to see errors
- Telegram — alerts arrive to subscribers of the Conversion send failures role.
- Notifications — subscription to this role is enabled in Settings → Notifications.
- Reminder frequency — to avoid receiving many identical messages during a stream of errors, the «how often to repeat the alert» window is configured in Connections → Telegram: the first message arrives immediately, then a single summary once per the chosen period.
