Event Name

An event name is the string that groups every occurrence of the same action under one label, and it is the key every event report is built on.

Grouping is done by exact string match, so case and separators matter and AddToCart, add_to_cart and add to cart are three separate events. Distinguish the raw name from the display label: the raw name is what the code sends and what is stored, while the display label lives only in the interface and changing it does not touch the data. The expensive mistake is renaming in code: the old name keeps its history and the new one starts empty, and every trend chart stays broken until the two are merged.
