    WHAT THIS ENABLES

    Tencent COS to Meta Offline CAPI

    Meta Offline CAPI for Tencent COS: Signals credits dealer, branch, and phone sales to the Meta campaigns behind them straight from your Tencent COS objects, hashed and consent-screened each time a new file lands.

    • Offline and in-store sales from your Tencent COS objects activated for Meta, as Signals credits dealer, branch, and phone sales to the Meta campaigns behind them.
    • In-store and phone revenue joining Meta's optimization loop, drawn from your Tencent COS objects by teams running Tencent Cloud COS.
    WHAT FLOWS WHERE

    The click, the conversion, and the credit.

    The conversion happens off Meta, away from any pixel. Here is how Tencent COS closes the loop.

    WHO THIS IS FOR

    Considered-purchase brands closing revenue far from the browser, with the records already in Tencent Cloud COS buckets and objects.

    Teams running Tencent Cloud COS activating Meta's offline optimization straight from Tencent COS objects.

    HOW DATAHASH SETS IT UP

    From kickoff to verified events.

    1. Connect

      A read-only key scoped to the Tencent COS bucket you name to feed Meta's Offline Conversions API, sized for Meta's 62-day event window.

    2. Map

      Signals picks up your Tencent COS objects, and its columns map to Meta's Offline Conversions API in the visual mapper, hashed and checked for Meta's 62-day event window.

    3. Deliver

      On each run, Signals pulls your Tencent COS objects, credits dealer, branch, and phone sales to the Meta campaigns behind them, and processes only the newly dropped file, with Meta's 62-day event window in the debugger.

    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 Tencent COS records the event.

    FAQ

    Asked on almost every call.

    How often does the Tencent COS Meta Offline CAPI sync run?

    The pace follows your Tencent COS objects: Signals sends changes from Tencent COS to Meta each time a new file lands. Because it processes only the newly dropped file, in-store and phone revenue joining Meta's optimization loop stays current while teams running Tencent Cloud COS keep Meta's 62-day event window in view. Delivery needs no export and no manual upload.

    What match rate should a Tencent COS-sourced Meta Offline CAPI batch expect?

    Coverage of hashed identifiers across your Tencent COS objects decides it, and teams running Tencent Cloud COS own that inside Tencent COS. A live email or phone matches into Meta; neither, and it will not. First-run feedback flags Meta's 62-day event window, which teams running Tencent Cloud COS then raise inside your Tencent COS objects.
