Project Details:
📘 Project Overview
The client—a Shopify-based DTC brand—was missing key conversion data due to browser limitations, iOS restrictions, and low signal reliability.
We implemented a server-side TikTok Conversion API setup via GTM Server Container, integrating events like , hosted on Stape.io. Events like page_view, view_category, add_to_cart, checkout, and purchase were tracked exclusively via server. This setup restored signal integrity, enhanced TikTok’s machine learning, and unlocked smarter ad delivery.
🚦The Challenges —–
Prior to Pixel implementation, the client faced:
⚠️ Poor event match quality (low EMQ scores)
⚠️ Low signal match rate and missing events in TikTok Events Manager
⚠️ Pixel-only setup failing due to browser restrictions (iOS, ad blockers)
⚠️ No server-side validation or deduplication logic
⚠️ Poor optimization due to incomplete data
⚠️ No first-party domain setup for trusted data flow
⚠️ GTM container not optimized for Meta tracking
These problems lead to underreporting, lost conversion, and wasted ad spend.
🎯 Our Solution
We built a dual-layer tracking system using TikTok Pixel (browser) and CAPI (server) via GTM. Server events were sent using a GTM Server container hosted on Stape.io, enriched with dynamic parameters (value, currency, IDs), and deduplicated using event_id.
