    FAQ

    Asked on almost every call.

    How often does the MongoDB TikTok Custom Audience sync run?

    The pace follows your MongoDB collections: Signals sends changes from MongoDB to TikTok each time the read runs. Because it reads only the records changed since the last run, TikTok custom audiences mirroring the segment your data team publishes stays current while application teams running MongoDB keep match quality on TikTok in view. Delivery needs no export and no manual upload.

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

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