Designing a useful button_click event payload

Source: interviewintermediate

WHAT IT TESTS: Event instrumentation design. OUTLINE: Include identity, timestamp, and context plus properties like button id, screen, and state; govern with a naming convention. RED FLAG: A bare event name, or ad hoc field names per event.

WHAT IT TESTS: Whether you instrument events so they answer real questions later. ANSWER OUTLINE: A good payload carries who (user id, anonymous or device id), when (event and received timestamps), and what (a clear event name) plus context: button id and label, screen, app version, platform, session id, and relevant state like cart value. Structure as a stable event name with a typed properties object, governed by a tracking plan. RED FLAG: Logging just the event name, inventing field names per event, or omitting identity and timestamp.
