      Columns from your ClickHouse tables align to OpenAI's Offline Conversions API in the visual mapper, hashed as the read runs and checked for the emerging OpenAI ad surface.

    3. Deliver

    WHAT YOU GET

    What changes when the CSV goes away.

    Capability Manual CSV upload Datahash
    Reporting Offline sales sit in a separate export, reconciled by hand. Revenue counted in the same Offline CAPI reporting as web conversions.
    Deduplication A re-uploaded file risks counting the same conversion twice. Deduped delivery, so a resent record never counts as a second conversion.
    Match visibility Match quality is a guess until the numbers look off. Match rate reported per upload, tied to the source event set that produced it.
    Effort and latency An analyst exports and uploads on a manual cadence. Server-side and automatic the moment Clickhouse records the event.

    FAQ

    Asked on almost every call.

    How often does the ClickHouse OpenAI Offline CAPI sync run?

    The pace follows your ClickHouse tables: Signals sends changes from ClickHouse to OpenAI each time the read runs. Because it reads only the records changed since the last run, a revenue feed ready the moment OpenAI's offline measurement expands stays current while analytics engineers on ClickHouse keep the emerging OpenAI ad surface in view. Delivery needs no export and no manual upload.

    What match rate should a ClickHouse-sourced OpenAI Offline CAPI batch expect?

    In ClickHouse, match rate tracks the email and phone quality your ClickHouse tables carry. Clean identifiers land for OpenAI; blank ones never will. The first Offline Conversions API report shows analytics engineers on ClickHouse where the emerging OpenAI ad surface needs work, a data-quality task handled in ClickHouse.
