Global event mappings apply to every destination. When you need one destination to behave differently — skip a mapping, change its rules, or get an event no other destination receives — you do that on the destination itself.

Prerequisites

Open the Event Mappings tab

Open the destination from Event Destinations, then select the Event Mappings tab.
The Event Mappings tab appears only after a destination is saved, and it isn’t available for Google Ads (Google Ads uses Conversion Actions instead).
The tab has two sections:
  • Inherited Mappings — the global mappings this destination receives.
  • Custom Triggers — mappings that belong to this destination only.

Adjust an inherited mapping

Open the Inherited Mappings section to see every global mapping this destination inherits. For any one of them you can:
  • Turn it off for this destination — use the switch next to the mapping. The mapping keeps working everywhere else; this destination just stops receiving it.
  • Override it — click Override to make a copy you can edit just for this destination. The destination then follows your copy instead of the global version.
Turning a mapping off here only affects this one destination. The global mapping still fires and still reaches your other destinations and your reporting.

Add a destination-only custom trigger

Open the Custom Triggers section and click Add Custom Trigger to create a mapping that only this destination receives. It uses the same editor as global mappings — set a Name, Source Event, Destination Event Name, Priority (1-100), and conditions — then click Create Trigger. Each custom trigger in the list can be switched on or off, edited, or removed at any time.

Save your changes

Changes on the Event Mappings tab are staged until you save. Click Update Configuration to apply them to the destination.

Which mapping wins

When a destination has its own version of a mapping, that version takes over for that destination:
  • A destination override beats the inherited global mapping — for that one destination.
  • Everywhere else, the global mapping still applies as usual.

Global event mappings

Create a mapping once and send it to every destination.
