Usage Event Ingestion — Accepts raw usage events over an API — API calls, jobs, messages, whatever the meter counts — with validation and acknowledgment. It is the front door of the metering pipeline; everything downstream, from deduplication to rating, only sees what it lets in.
Where it sits in the lifecycle
Usage Event Ingestion (API) lives in the Consume & Meter phase
of Fulfill & Bill — the stage where you activate what was sold, meter what's used, bill it right.
In the corpus tool index this phase maps to the Meteringcategory.
