Track an anonymous event

An anonymous event represents a person you haven't identified yet. When you identify a person, you can set their anonymous_id attribute. If event merging is turned on in your workspace, and the attribute matches the anonymous_id in one or more events that were logged within the last 30 days, we associate those events with the person. If you associate an event with a person within 72 hours of the timestamp on the event, you can trigger automations from the event.

There are three possible event type values: page, screen and event. Page and screen events represent website page views and mobile app screen views respectively; the name for these event types is intended to be the page or screen a person visited or viewed. Any other event, is given the event type.

Note: Avoid using names with leading or trailing spaces, because you can't reference event names with leading or trailing spaces in automations, etc. In workspaces created after September 21, 2021, we trim leading and trailing spaces from event names automatically to fix this issue.
