    WHAT THIS ENABLES

    Redshift to Snapchat Offline CAPI

    Redshift to Snapchat Offline CAPI: The Redshift Data API reads the offline and in-store sales in your Redshift tables, and Signals reports in-store purchases against the Snapchat campaigns that reached the buyer, hashed and consent-checked as the materialized view refreshes.

    • Signals reports in-store purchases against the Snapchat campaigns that reached the buyer, reading your Redshift tables as the materialized view refreshes.
    • Physical-world sales counted inside Snapchat performance, fed by analytics teams maintaining Redshift tables and materialized views.
    WHAT FLOWS WHERE

    The click, the conversion, and the credit.

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

    Snap credits the campaign that sourced the conversion conversion happens off-platform Ad click on Snap R Scheduled read sync recorded in Redshift 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 numbers already modeled in Redshift tables and materialized views.

    Analytics teams maintaining Redshift tables and materialized views who need physical-world sales counted inside Snapchat performance.

    HOW DATAHASH SETS IT UP

    From kickoff to verified events.

    1. Connect

      A scoped IAM role with SELECT on the schema you name to feed Snapchat's Conversions API, sized for offline event timing.

    2. Map

      The Redshift Data API reads your Redshift tables, and its columns map to Snapchat's Conversions API in the visual mapper, hashed and checked for offline event timing.

    3. Deliver

      As the materialized view refreshes, Signals reports in-store purchases against the Snapchat campaigns that reached the buyer, touches only the rows changed since the last read, with offline event timing watched 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 Redshift records the event.

    FAQ

    Asked on almost every call.

    How often does the Redshift Snap Offline CAPI sync run?

    The refresh schedule drives it: when the materialized view rebuilds nightly, Snapchat gets a nightly feed, and an hourly refresh runs hourly. Each read touches only changed rows, so physical-world sales counted inside Snapchat performance stays fresh for offline event timing without RA3 load rising.

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

    The fill rate of the view matters more than Redshift itself. A clean hashed email or phone matches; a blank one never will. The first scheduled read reports quality from Snapchat's Conversions API, the figure retail and QSR advertisers whose Snapchat audience buys in person weigh against offline event timing.
