  title: Amberflo Create Meter and Ingest Event
  summary: Create a meter definition and immediately ingest a usage event against it.
  description: >-
    The foundational metering setup flow. It creates a new meter definition for
    a given aggregation type, then ingests a first meter event against that meter
    for a customer so that downstream usage queries have data to report. Every
    step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
