Server-side CAPI & deduplication

Dual delivery sends each event from both the browser and your server, then relies on a shared event ID for accurate counting.

Steps

1. 1

   Browser pixel fires

   The web pixel extension records the event in the browser and sends a beacon to the app backend.

2. 2

   Server posts to CAPI

   The backend posts the same event to the TikTok Conversion API endpoint, including hashed customer data.

3. 3

   TikTok deduplicates

   Because both hits share one event ID, TikTok merges them and counts the conversion only once.
