    FAQ

    Asked on almost every call.

    How often does the File drops TikTok Custom Audience sync run?

    You set the cadence, from near-real-time to a nightly File drops sync of your file drops into TikTok. Since Signals processes only the newly dropped file, TikTok custom audiences mirroring the segment your data team publishes keeps pace and teams landing POS and back-office exports as files watch match quality on TikTok. One scoped connection sets it up, cadence adjustable later.

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

    In File drops, match rate tracks the email and phone quality your file drops carry. Clean identifiers land for TikTok; blank ones never will. The first Custom Audience API report shows teams landing POS and back-office exports as files where match quality on TikTok needs work, a data-quality task handled in File drops.
