Conversions API

TikTok Events API
Server-side, in 15 minutes.

Ship purchases and leads straight to TikTok Events API 2.0 — deduplicated with the Pixel, iOS-proof.

TikTok's Events API 2.0 endpoint with full event_id deduplication, ttclid capture, Advanced Matching, and EMQ diagnostics. Works alongside the TikTok Pixel or fully replaces it.

Why server-side for TikTok Events API

EMQ 75+ out of the box

TikTok's quality score starts high with auto-hashed em/ph/ttclid/external_id.

Events API 2.0 ready

Uses the newer /event/track/ endpoint — older /track/ is deprecated by TikTok end of 2025.

Dedupe with Pixel

Same event_id as the TikTok Pixel prevents inflated conversion counts.

Events tracked out of the box

Standard TikTok Events API events mapped automatically. Custom events supported via the same endpoint.
