After the definition of product events, there comes the definition of interaction events - only one level deeper.
Usually, interaction events are not put into a tracking plan, as it is not important to document at the smallest kinds of interactions.
In case of interaction events, we recommend making use of auto-tracking. Because interaction events or activities are most detailed. Interaction events can show how users or customers interact with your services and/ or they are often used in order to describe discovery or research tasks. You can differentiate interaction events from product or business events by their level of granularity. An example of an interaction event might serve as a CTA. As CTA activity it can be defined 'clicked' and as CTA properties people might describe 'placement', 'target' or 'text'.
