    WHAT THIS ENABLES

    Attio to Meta Offline CAPI

    Meta Offline CAPI for Attio: Signals credits dealer, branch, and phone sales to the Meta campaigns behind them straight from your Attio workspace lists, hashed and consent-screened as records change.

    • Offline and in-store sales from your Attio workspace lists 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 Attio workspace lists by RevOps teams running Attio.
    WHAT FLOWS WHERE

    The click, the conversion, and the credit.

    HOW DATAHASH SETS IT UP

    From kickoff to verified events.

    1. Connect

      Scoped OAuth access to Attio, reading only your Attio workspace lists to feed Meta's Offline Conversions API, sized for Meta's 62-day event window.

    2. Map

      Signals reads your Attio workspace lists, 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 Attio workspace lists, credits dealer, branch, and phone sales to the Meta campaigns behind them, and sends only the records that changed, 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 Attio records the event.

    FAQ

    Asked on almost every call.

    How often does the Attio Meta Offline CAPI sync run?

    The pace follows your Attio workspace lists: Signals sends changes from Attio to Meta as records change. Because it sends only the records that changed, in-store and phone revenue joining Meta's optimization loop stays current while RevOps teams running Attio keep Meta's 62-day event window in view. Delivery needs no export and no manual upload.

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

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