    WHAT THIS ENABLES

    GCS to Snapchat Custom Audience

    GCS to Snapchat Custom Audience: your GCS objects, hashed and consent-checked, feed Snapchat as Signals matches your segments into Snapchat for targeting and customer suppression each time a new file lands.

    • Customer segments from your GCS objects activated for Snapchat, as Signals matches your segments into Snapchat for targeting and customer suppression.
    • Snapchat audiences that stay in step as the segment rebuilds, drawn from your GCS objects by data teams landing exports in GCS.

    WHAT FLOWS WHERE

    GCS to Custom Audience, mapped.

    Each sync hands the customer segments from your GCS objects to Signals, which hashes and filters every record, then Snapchat's Custom Audiences API logs the match-ready audiences for list sizing on Snapchat.

    WHO THIS IS FOR

    Built for the teams that own the number.

    Snapchat advertisers building lookalikes and excluding current buyers, with the records already in Google Cloud Storage buckets and objects.

    Data teams landing exports in GCS activating Snapchat audience matching straight from GCS objects.

    HOW DATAHASH SETS IT UP

    From kickoff to verified events.

    1. Connect

      A read-only service account scoped to the one GCS bucket you name to feed Snapchat's Custom Audiences API, sized for list sizing on Snapchat.

    2. Map

      Signals picks up your GCS objects, and its columns map to Snapchat's Custom Audiences API in the visual mapper, hashed and checked for list sizing on Snapchat.

    3. Deliver

      On each run, Signals pulls your GCS objects, matches your segments into Snapchat for targeting and customer suppression, and processes only the newly dropped file, with list sizing on Snapchat in the debugger.

    WHAT YOU GET

    What ships with this use case.

    Snapchat audiences that stay in step as the segment rebuilds on every run, as Signals reads your GCS objects and processes only the newly dropped file.

    Audiences that rebuild as the segment does from your GCS objects, with transfer overhead steady because Signals processes only the newly dropped file.

    A per-run match report from Snapchat's Custom Audiences API on list sizing on Snapchat, straight out of your GCS objects.

    FAQ

    Asked on almost every call.

    How often does the GCS Snap Custom Audience sync run?

    The pace follows your GCS objects: Signals sends changes from GCS to Snapchat each time a new file lands. Because it processes only the newly dropped file, Snapchat audiences that stay in step as the segment rebuilds stays current while data teams landing exports in GCS keep list sizing on Snapchat in view. Delivery needs no export and no manual upload.

    What match rate should a GCS-sourced Snap Custom Audience batch expect?

    Coverage of hashed identifiers across your GCS objects decides it, and data teams landing exports in GCS own that inside GCS. A live email or phone matches into Snapchat; neither, and it will not. First-run feedback flags list sizing on Snapchat, which data teams landing exports in GCS then raise inside your GCS objects.
