# Ingest Impression Event

**POST /v1/internal/impressions/ingest**

Ingest one impression/click event onto the publish queue.

The request context (IP/UA) is the gateway's, not the end user's — the
gateway derives ``user_fingerprint``/``device_type`` at its edge from the
user's actual request and forwards only those derivatives (no raw PII). The
strong attribution key is ``tracking_id``, landed on ``click_id`` — the
join rail impression rows, click rows, and (later) network conversion
reports all share.
