    CONNECTIONS / MongoDB / MongoDB to Snap Custom Audience

    From MongoDB collections to Snapchat audience matching.

    Signals reads your MongoDB collections through a read-only database user scoped to the MongoDB collections you name, then matches your segments into Snapchat for targeting and customer suppression so Snapchat sees match-ready audiences without an export.

    WHAT THIS ENABLES

    MongoDB to Snapchat Custom Audience

    MongoDB to Snapchat Custom Audience: Signals reads your MongoDB collections and matches your segments into Snapchat for targeting and customer suppression, hashed and consent-checked each time the read runs.

    • Signals matches your segments into Snapchat for targeting and customer suppression, reading your MongoDB collections each time the read runs.
    • Audiences that rebuild as the segment does, with no export step out of your MongoDB collections.

    WHAT FLOWS WHERE

    MongoDB to Custom Audience, mapped.

    Each sync hands the customer segments from your MongoDB collections 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, working out of MongoDB collections and aggregation views.

    Application teams running MongoDB who need Snapchat audiences that stay in step as the segment rebuilds out of MongoDB collections.

    HOW DATAHASH SETS IT UP

    From kickoff to verified events.

    1. Connect

      A read-only database user scoped to the MongoDB collections you name, mapped to Snapchat's Custom Audiences API and tuned for list sizing on Snapchat.

    2. Map

      Columns from your MongoDB collections align to Snapchat's Custom Audiences API in the visual mapper, hashed as the read runs and checked for list sizing on Snapchat.

    3. Deliver

      Each time the read runs, Signals reads your MongoDB collections and matches your segments into Snapchat for targeting and customer suppression, reads only the records changed since the last run, with list sizing on Snapchat watched in the debugger.

    WHAT YOU GET

    What ships with this use case.

    Snapchat audiences that stay in step as the segment rebuilds from your MongoDB collections, delivered each time the read runs.

    Audiences that rebuild as the segment does out of your MongoDB collections, delivered each time the read runs without read load on the database climbing.

    Match feedback on list sizing on Snapchat from Snapchat's Custom Audiences API each run, tied back to your MongoDB collections.

    FAQ

    Asked on almost every call.

    How often does the MongoDB Snap Custom Audience sync run?

    The pace follows your MongoDB collections: Signals sends changes from MongoDB to Snapchat each time the read runs. Because it reads only the records changed since the last run, Snapchat audiences that stay in step as the segment rebuilds stays current while application teams running MongoDB keep list sizing on Snapchat in view. Delivery needs no export and no manual upload.

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

    In MongoDB, match rate tracks the email and phone quality your MongoDB collections carry. Clean identifiers land for Snapchat; blank ones never will. The first Custom Audiences API report shows application teams running MongoDB where list sizing on Snapchat needs work, a data-quality task handled in MongoDB.
