  title: Amplitude Ingest Events and Segment
  summary: Upload a batch of events through the HTTP V2 API, then query event segmentation to verify the metric.
  description: >-
    A round-trip data-quality flow that sends a batch of events into Amplitude
    through the HTTP V2 ingestion endpoint and then queries the Dashboard REST
    event segmentation endpoint for the same event type to confirm the data is
    being counted. The ingestion step branches on the returned code so the
    segmentation query only runs after events were accepted. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.

  description: >-
    Sends a batch of events for a user, confirms the ingestion code, and then
    runs an event segmentation query over a date window to retrieve totals or
    unique counts for the ingested event type.
