This API aggregates top-level metrics associated with conversion events.
Conversion events are delivered through /cce/push or with the sendConversionEvent function. Each conversion event represents the actual "raw" fact of a conversion/renewal/termination of a user (funnel steps "convertProduct", "renewProduct" and "terminateProduct") OR any other custom funnel step in the conversion funnel (if needed) and is associated with a conversion product. Implementation guide for such events can be found here.
The API uses the same request, response and limitations as for /traffic, except that that the only fields that can be aggregated are events and uniqueUsers, where events is an implicit field and the uniqueUsers field has to be specified explicitly.
