Likeid

Likeid is a term that does not denote a single, universally defined concept, but is used informally in discussions of social media data and engagement analytics to refer to the unique identifier assigned to an individual "like" action. In many systems, when a user likes a post, an event record is created that includes fields such as like_id, user_id, post_id, and a timestamp. The like_id serves as a stable reference to that specific reaction, enabling operations such as undoing the like, auditing interactions, or joining engagement data with user and content records.

The exact naming and schema for a like identifier vary across platforms and implementations. Some systems may call it likeEventId, reactionId, or simply like_id, and the scope of the identifier can differ depending on whether the design treats likes as separate objects or as part of a broader engagement event. In data processing and APIs, like IDs help distinguish individual interactions within large streams of activity, while supporting privacy and data governance by separating action identifiers from personally identifiable information.

In practice, the concept of a like identifier is closely tied to engagement metrics, event logging, and data linking. There is no formal standard for how like identifiers should be structured or used, so definitions and implementations are platform-specific and evolve with analytics and product requirements.
