    WHAT THIS ENABLES

    Box to Snapchat Offline CAPI

    Box to Snapchat Offline CAPI: Signals reads your Box files and reports in-store purchases against the Snapchat campaigns that reached the buyer, hashed and consent-checked each time a new file lands.

    • Offline and in-store sales from your Box files activated for Snapchat, as Signals reports in-store purchases against the Snapchat campaigns that reached the buyer.
    • Physical-world sales counted inside Snapchat performance, drawn from your Box files by ops teams sharing exports in Box.
    WHAT FLOWS WHERE

    The click, the conversion, and the credit.

    The conversion happens off Snap, away from any pixel. Here is how Box closes the loop.

    Snap credits the campaign that sourced the conversion conversion happens off-platform Ad click on Snap File drop sync recorded in Box S Signals hash · dedupe Conversions API delivered · credited
    WHO THIS IS FOR

    Built for the teams that own the number.

    Retail and QSR advertisers whose Snapchat audience buys in person, with the records already in Box folders and shared exports.

    Ops teams sharing exports in Box activating Snapchat in-store conversions straight from Box files.

    HOW DATAHASH SETS IT UP

    From kickoff to verified events.

    1. Connect

      Read-only OAuth access to the Box folder you name to feed Snapchat's Conversions API, sized for offline event timing.

    2. Map

      Signals picks up your Box files, and its columns map to Snapchat's Conversions API in the visual mapper, hashed and checked for offline event timing.

    3. Deliver

      On each run, Signals pulls your Box files, reports in-store purchases against the Snapchat campaigns that reached the buyer, and processes only the newly dropped file, with offline event timing 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 Box records the event.

    FAQ

    Asked on almost every call.

    How often does the Box Snap Offline CAPI sync run?

    Delivery tracks Box, run by ops teams sharing exports in Box: a near-real-time or scheduled sync of your Box files feeds Snapchat on that cadence. Each run processes only the newly dropped file, so in-person conversions Snapchat can bid on holds up on offline event timing. The live debugger confirms every delivery inline.

    What match rate should a Box-sourced Snap Offline CAPI batch expect?

    Match rate follows identifier coverage in your Box files, which ops teams sharing exports in Box control, not Box itself. A record with a current hashed email or phone matches for Snapchat; one missing both cannot. First-run feedback from Conversions API pinpoints offline event timing, the number ops teams sharing exports in Box tune against.
