sessionId property

String? sessionId
getter/setter pair

A unique identifier for tracking a visitor session with a length limit of 128 bytes.

A session is an aggregation of an end user behavior in a time span. A general guideline to populate the sesion_id: 1. If user has no activity for 30 min, a new session_id should be assigned. 2. The session_id should be unique across users, suggest use uuid or add visitor_id as prefix.

Implementation

core.String? sessionId;
