# Event Reference ### Canonical Shared Event Schema All domain-specific events include this shared base along with domain-specific extensions. ```typescript interface AnalyticsEvent { // Shared identifiers & timing /** * The difference between the client clock vs. server clock, * represented in milliseconds. */ clockDriftInMs: number; /** * ISO 8601 timestamp from client clock, representing the timestamp * when the event was fired. */ eventDate: string; /** * Universally unique event id, in UUID v4 format. */ eventId: string; /** * The distinct, domain-specific type of event. */ eventType: string; /** * The current visitor's locale setting in a multi-language environment. */ locale?: string; /** * Distinct store identifier in a multi-store/multi-region environment. */ storeRef?: string; /** * The distinct visitor identifier, if provided by the host app or * environment. */ visitorExternalId?: string; /** * The universally, LiSA-assigned visitor identifier, * in UUID v4 format. */ visitorId?: string; /** * The universally, LiSA-assigned visitor session identifier, * in UUID v4 format. */ visitorSessionId?: string; // If applicable to the event /** * The universally unique identifier of the media item, * this event is associated with, in UUID v4 format. */ mediaItemId?: string; /** * The distinct type of media item, this event is associated with. */ mediaItemType?: 'live' | 'replay' | 'story'; /** * An object, representing the current media item's playback progress. */ progress?: { /** * Indicates, whether the current media item is a live stream or * recorded. */ isLive: boolean; /** * Indicates whether the current media item playback is active. */ isPlaying: boolean; /** * The current media item's playback position, * represented in milliseconds. */ currentTimeInMs: number; /** * The current media item's total duration (-1 for live), * represented in milliseconds. */ durationInMs: number; /** * The accumulated watch time, represented in milliseconds. */ elapsedTimeInMs: number; }; } ``` {% hint style="warning" %} Domain-specific events (e.g., product clicks) augment this with their own fields; those go into contextData as well or into commerce-specific variables when appropriate. {% endhint %} ### Events
