Zernio stored an event: one sent to POST /v1/events or POST /v1/ads/conversions, or one a connected source sent for you (a lead form lead, a Shopify or WooCommerce order, a HubSpot deal). It fires again when a newer version of the same event is stored, such as an order that changed.

conversion has the fields of GET /v1/events/{eventId}, plus source, campaign (the campaign the event counts for, or null) and campaignMatch (why there is none). Personal data is never sent: hasEmail, hasPhone and hasExternalId only say what the event carried.

Deduplication

The event id follows the stored event and its version, so a resend of the same version carries the same id. Deduplicate on it.

Not sent for

Test events (they are never stored), corrections made with PATCH or DELETE /v1/events/{eventId}, and the hourly re-match that ties an earlier event to its campaign.
