Track an Event

Tracks an event for the current user

Events (also known as activities) are used to indicate that one of your site's visitors performed a particular action. These events will appear in that user's profile as recent history and can be used to create behaviors for triggers and segmentation within the Zeta Marketing Platform. As well, these events act as signals for Zeta's personalization systems to generate insights and predictive recommendations for your campaigns.

Event tracks are non-blocking JavaScript calls.

bt('track', eventType, properties, settings={});

The track call has the following fields:

FieldTypeDescription
eventTypeStringThe name of the event, e.g. "viewed", "liked", "shared".
propertiesObjectA JSON object containing key:value pairs indicating properties to be tracked as metadata in this event. See Properties below for more information. An empty JSON object {} should be provided if there are no properties to be tracked with the event.
settings optionalObjectSettings specific to this event. Currently supports specification of onComplete, onSuccess, and onFailure callback functions. See Settings below for more information.
