    CONNECTIONS / Apache Cassandra / Apache Cassandra to Snap Offline CAPI

    From Cassandra tables to Snapchat in-store conversions.

    Connect Apache Cassandra and point Signals at your Cassandra tables; it reports in-store purchases against the Snapchat campaigns that reached the buyer each time the read runs, hashed and consent-checked for Snapchat.

    WHAT THIS ENABLES

    Apache Cassandra to Snapchat Offline CAPI

    Apache Cassandra to Snapchat Offline CAPI: Signals reads your Cassandra tables and reports in-store purchases against the Snapchat campaigns that reached the buyer, hashed and consent-checked each time the read runs.

    • Offline and in-store sales from your Cassandra tables 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 Cassandra tables by platform teams running Cassandra.
    WHAT FLOWS WHERE

    The click, the conversion, and the credit.

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

    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 Cassandra tables and materialized views.

    Platform teams running Cassandra activating Snapchat in-store conversions straight from Cassandra tables.

    HOW DATAHASH SETS IT UP

    From kickoff to verified events.

    1. Connect

      A read-only database user scoped to the Cassandra tables you name to feed Snapchat's Conversions API, sized for offline event timing.

    2. Map

      A scheduled read pulls your Cassandra tables, 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 Cassandra tables, reports in-store purchases against the Snapchat campaigns that reached the buyer, and reads only the records changed since the last run, 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 Apache Cassandra records the event.
    ON THE WIRE

    FAQ

    Asked on almost every call.

    How often does the Apache Cassandra Snap Offline CAPI sync run?

    You set the cadence, from near-real-time to a nightly Apache Cassandra sync of your Cassandra tables into Snapchat. Since Signals reads only the records changed since the last run, physical-world sales counted inside Snapchat performance keeps pace and platform teams running Cassandra watch offline event timing. One scoped connection sets it up, cadence adjustable later.

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

    In Apache Cassandra, match rate tracks the email and phone quality your Cassandra tables carry. Clean identifiers land for Snapchat; blank ones never will. The first Conversions API report shows platform teams running Cassandra where offline event timing needs work, a data-quality task handled in Apache Cassandra.
