## TL;DR

Omitting idempotencyKey on events causes rejections or duplicate counting: it is required. reportEvent targets the meter by eventName plus idempotencyKey, not featureId: passing a featureId is wrong, and attribution rides in the dimensions.

1. Omitting idempotencyKey on events causes rejections or duplicate counting: it is required. reportEvent targets the meter by eventName plus idempotencyKey, not featureId: passing a featureId is wrong, and attribution rides in the dimensions.
