Pinterest Ads integration

Pinterest Ads in Polar: spend in, real signal out.

Connect Pinterest Ads and ad spend, delivery and campaign performance flow into Polar's blended ROAS, MER and CAC, next to Meta, Google and the rest. Then the CAPI Enhancer sends first-party, de-duplicated conversions back so the algorithm optimizes on signal the browser loses.

Pinterest Ads gives you Pinterest Ads's number. Your business is one.

Pinterest Ads reports its own performance in isolation, before dedup, and it cannot see the rest of your stack or tell you what is incremental. Polar can.

Pinterest Ads on its own

  • ROAS is Pinterest Ads's number, before dedup, so it overclaims.
  • No blend with Meta, Google, Shopify or email.
  • No read on whether the spend is incremental.
  • Nothing reconciles against your real P&L.

Pinterest Ads with Polar

  • Blended ROAS and MER after overclaiming is removed.
  • First-party conversions sent back via the CAPI Enhancer.
  • Geo-based incrementality proves the real lift.
  • Every dollar reconciled into blended CAC and margin.

The Gap

The connector is only half of it.

Once your Pinterest Ads spend and performance are connected to 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

Judged on the whole business.

Judged on the whole business

Pinterest Ads looks however Pinterest Ads wants it to look in its own dashboard: ROAS before dedup, credit for conversions other channels also claim, and no idea what is truly incremental. Polar folds Pinterest Ads into blended ROAS, MER and CAC next to every other channel, sends first-party conversions back with the CAPI Enhancer so the algorithm optimizes on real signal, and lets you run a geo-based incrementality test to prove how much of the revenue you would not have earned anyway. You stop scaling on a platform's self-report and start scaling on causation.

What makes it real

Deduplicated ROAS. Pinterest Ads after overclaiming is removed, blended with every channel.

Incrementality. Geo-based holdouts prove the real lift, independent of Pinterest Ads.

Ask Polar, in plain language. “Show Pinterest Ads's blended ROAS after dedup and my last incrementality read.” No SQL, no export.
