TikTok Events API (CAPI)

TikTok Sees Your Views.
We Make It See Your Buyers.

iOS restrictions and browser limitations mean TikTok’s pixel misses 60%+ of your purchasers. Server-side Events API sends that data directly from your server — no browser required.

The Problem

Your TikTok pixel is only seeing a fraction of your buyers.

Server-side events fix the three reasons TikTok attribution breaks:

60%+

iOS users are invisible to your TikTok pixel

Safari’s ITP and iOS App Tracking Transparency block pixel tracking. If your buyers use iPhones — and most do — TikTok’s algorithm is flying blind for the majority of your audience.

15%

Typical pixel-only match rate for purchases

TikTok’s algorithm needs high-quality purchase signals to find more buyers like your customers. At 15% match rate, it’s optimizing on bad data — wrong lookalike, wrong delivery, wrong ROAS.

Ad Blocker

Ad blockers kill remaining pixel events

Even Android users with ad blockers or privacy browsers suppress your TikTok pixel. Server-side Events API sends from your server directly to TikTok — completely bypass browser restrictions.

Real Client Result

Same campaigns. Now TikTok can actually see who’s buying.

“Our TikTok ads were showing 2% purchase attribution. WebDataSolve set up the Events API in 4 days. Within 3 weeks TikTok’s algorithm completely changed who it was showing our ads to — ROAS went from 0.8x to 2.7x.”

How It Works

From broken pixel to 90%+ match rate in 4 steps.

1
TikTok Pixel Audit
We review your current pixel implementation, check which events are firing correctly, identify gaps in purchase tracking, and calculate your current match quality score.
2
Server-Side Events API
We connect your server directly to TikTok’s Events API. Purchase, AddToCart, and ViewContent events are sent from your server — bypassing iOS restrictions and ad blockers entirely.
3
Event Deduplication
Both pixel and server send events. We configure deduplication so TikTok counts each event only once — no inflated data, no double attribution, just accurate purchase counts.
4
Match Rate Optimisation
We pass advanced match parameters — hashed email, phone, external ID, TikTok click ID — to maximise your match quality score and give TikTok the richest possible buyer signal.

TikTok CAPI FAQ

Questions about TikTok Events API.

CAPI (Conversions API) is TikTok’s server-side tracking solution. Instead of relying on a browser pixel that can be blocked by iOS, Safari ITP, or ad blockers, CAPI sends your conversion events from your server directly to TikTok. It dramatically improves match rates and gives TikTok’s algorithm better purchase data to optimise on.
Not necessarily. TikTok CAPI can be implemented directly via your platform (Shopify, WooCommerce) or server. However, having GTM already configured makes it cleaner and more maintainable. We scope the best approach during the free audit based on your current setup.
They solve the same problem (browser tracking loss) but for different platforms. TikTok uses Events API with a different deduplication mechanism (event_id + pixel_code). Meta uses their Conversions API with a separate deduplication ID. We configure both correctly if you run ads on both platforms.
TikTok scores match quality from 0–10. Under 5 is poor and means TikTok can’t reliably identify who converted. 7+ is good, 9+ is excellent. With pixel only, most stores sit between 2–4. With Events API and advanced matching configured properly, we consistently achieve 8.5–9.5.
No — pixel and CAPI work together, not instead of each other. The pixel handles browser-side events where it can; CAPI fills in what the pixel missed. Deduplication ensures each event is counted once. You get better data without losing existing attribution.
