Meta Ads integration

Meta Ads in Polar: the signal Meta's pixel loses, sent back.

Connect Meta once and spend, delivery and creative performance flow into Polar's blended ROAS, MER and CAC. Then the CAPI Enhancer sends 100% of your purchases back to Meta as enriched, first-party, de-duplicated events, so the algorithm optimizes on the conversions the browser dropped. And with geo-based incrementality testing, you can finally prove how much of Meta's revenue is actually incremental.

Meta gives you Meta's number. Your business is one.

Ads Manager reports Meta's ROAS in isolation, before dedup, on browser signal that iOS and ad blockers erode. It cannot see Google, TikTok, Shopify or email, and it cannot tell you what is incremental. Polar can.

Meta Ads on its own

  • ROAS is Meta's number, before dedup, so it overclaims against your other channels.
  • The pixel loses conversions to iOS, cookies and ad blockers, starving the algorithm.
  • No way to tell incremental revenue from what you'd have earned anyway.
  • Nothing reconciles against your real P&L.

Meta Ads with Polar

  • Blended ROAS and MER after platform overclaiming is removed, so the number is real.
  • The CAPI Enhancer sends 100% of purchases back to Meta CAPI, enriched and first-party.
  • Geo-based incrementality testing proves how much of Meta's revenue is truly incremental.
  • Every Meta dollar reconciled into blended CAC, contribution margin and net profit.

Turn on the CAPI Enhancer ~2 min

100% first-party events, back to Meta.
The CAPI Enhancer captures purchases through the Polar Pixel, enriches them with order detail, customer IDs and hashed emails, and delivers them server-side via Meta CAPI, ensuring 100% event delivery with proper deduplication.
One CAPI at a time: you cannot run two Meta CAPI solutions at once, they create incompatible event IDs and double-count. Polar's replaces, it does not stack.

Prove the lift the payoff

Incrementality, not just ROAS.
Run a geo-based incrementality test (GeoLift) to prove how much of Meta's revenue is truly incremental, independent of Meta's own attribution. Results in about two weeks.
Get started

Feed Meta the conversions its pixel can't see.

Connect Meta for blended reporting, turn on the CAPI Enhancer for 100% first-party event delivery, and run incrementality tests to prove the lift.

The Gap

The connector is only half of it.

Once your Meta spend and conversions are clean and attributed inside Polar, you can use them wherever you already work. Ask Polar in plain language, pull them live through the Polar MCP, or schedule a snapshot into the report your team reads every morning.

Featured Use Case

Prove Meta is actually incremental.

Incrementality, finally measured

Every Meta buyer has had the argument: Meta says it drove the revenue, but how much of it would have happened anyway? ROAS cannot answer that, because it counts every conversion Meta can attribute, not the ones Meta actually caused. Polar's incrementality testing settles it with geo-based holdouts, GeoLift, splitting comparable regions and measuring the real lift, platform-agnostic and independent of Meta's own numbers. In about two weeks you get a defensible read on how much of Meta's revenue is incremental, so you scale on causation, not correlation. And because the CAPI Enhancer is already feeding Meta 100% first-party events, the ROAS you see alongside it is deduplicated and blended with every other channel.

What makes it real

Geo-based holdouts. GeoLift splits comparable regions to measure true lift, independent of Meta's attribution.

100% event delivery. The CAPI Enhancer sends enriched, first-party purchases to Meta CAPI so the algorithm optimizes on real conversions.

Ask Polar, in plain language. “What's my real Meta ROAS after dedup, and how did my last incrementality test read?” No SQL, no export.
