Event Mapping

Event mapping is the set of per-ad-platform rules that decide how a conversion is sent out to each platform’s matching conversion action. It is the outbound half of how one tracked conversion stays consistent across Facebook, Google, TikTok, and others.

  • Conversion Mapping — event mapping is outbound (conversion → each ad platform’s action); conversion mapping is inbound (a source’s events → a standard conversion). The defining pair.
  • Conversion API — event mapping is the routing rule; the Conversion API is the channel that physically delivers the event.

After a conversion is normalized by Conversion Mapping, event mapping routes it outbound: a standard Purchase maps to Facebook Purchase, Google purchase, and TikTok CompletePayment. Custom conversions have no native platform equivalent, so event mapping is where you point each one at the right conversion action on every connected ad platform.
