How Fiat Achieved 31% Improvement in TikTok Event Tracking with Hardal EAPI

Fiat, operating through the TOFAŞ group in Turkey, was experiencing limitations in their TikTok advertising performance due to browser-based pixel tracking. Growing iOS privacy restrictions and browser limitations were impacting data accuracy, preventing complete customer journey capture and campaign optimization.

The solution was TikTok Events API implementation with server-side tracking infrastructure and comprehensive customer parameter matching.

Why Hardal?

Fiat was facing critical data loss from browser restrictions and ad blockers that prevented complete automotive shopping journey capture on TikTok. Traditional pixel-only tracking couldn't provide the comprehensive performance signals needed to optimize campaigns across the extended consideration cycles typical of vehicle purchases.

Hardal's TikTok EAPI solution established dual-layer tracking architecture that ensures complete data capture independent of browser limitations.

Key advantages delivered by Hardal:

• Server-side event tracking — Direct server-to-server integration capturing complete PageView and conversion data unaffected by browser restrictions
• Comprehensive customer matching — Enhanced parameters including name, gender, email, phone, postal code, and location data
• Dual-layer architecture — Combined browser pixel and server-side tracking for maximum data coverage
