    FAQ

    Asked on almost every call.

    How often does the GA4 Snap CAPI sync run?

    The pace follows your GA4 events: Signals sends changes from GA4 to Snapchat as each event fires. Because it forwards each event as it arrives, web conversions Snapchat can optimize on without pixel-only gaps stays current while analytics teams instrumenting GA4 keep server-and-pixel deduplication in view. Delivery needs no export and no manual upload.

    What match rate should a GA4-sourced Snap CAPI batch expect?

    In GA4, match rate tracks the email and phone quality your GA4 events carry. Clean identifiers land for Snapchat; blank ones never will. The first Conversions API report shows analytics teams instrumenting GA4 where server-and-pixel deduplication needs work, a data-quality task handled in GA4.
