    WHAT THIS ENABLES

    Box to Snapchat Custom Audience

    Box to Snapchat Custom Audience: Signals reads your Box files and matches your segments into Snapchat for targeting and customer suppression, hashed and consent-checked each time a new file lands.

    • Customer segments from your Box files 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 Box files by ops teams sharing exports in Box.

    WHAT FLOWS WHERE

    Box to Custom Audience, mapped.

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

    FAQ

    Asked on almost every call.

    How often does the Box Snap Custom Audience 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 audiences that rebuild as the segment does holds up on list sizing on Snapchat. The live debugger confirms every delivery inline.

    What match rate should a Box-sourced Snap Custom Audience 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 Custom Audiences API pinpoints list sizing on Snapchat, the number ops teams sharing exports in Box tune against.
