Pinterest Conversion API Setup to Maximize Revenue
Full-Funnel Event Tracking for Accurate, Compliant, and Privacy-Focused Conversions
💼 Project Summary
Client: Home Décor eCommerce Brand
Goal: Implement a robust browser + server-side tracking system for Pinterest Ads to ensure accurate conversion tracking, better optimization, and GDPR/CCPA compliance.
Project Details:
📘 Project Overview
The client—a growing DTC eCommerce brand—was relying solely on the Pinterest Tag for conversion tracking. As a result, they faced data loss from browser restrictions and inaccurate conversion reporting, especially from iOS traffic.
To solve this, we implemented a dual-channel tracking solution using Google Tag Manager (Web + Server), hosted on Stape.io. Key events such as page_visit, view_category, add_to_cart, checkout, and purchase were configured to fire both via the browser pixel and the Pinterest Conversion API (CAPI).this setup restored lost attribution, improved data reliability, and strengthened Pinterest’s bidding algorithm—driving better campaign performance across devices and platforms.
🚦The Challenges :
| Problem | Description |
|---|---|
| ❌ Browser pixel blocked | iOS and browser restrictions reduced conversion visibility |
| ❌ Poor data quality | Incomplete event parameters affecting campaign performance |
| ❌ No server tracking | Reliance on front-end only tracking created blind spots |
| ❌ Consent compliance gaps | No proper consent handling or privacy protection |
| ❌ Underperforming campaigns | Weak signal strength for Pinterest ad optimization |
📊 Key Events Tracked :
| Event | Sent via Pixel | Sent via Server | Parameters |
|---|---|---|---|
| page_visit | ✅ | ✅ | URL, user_agent |
| view_category | ✅ | ✅ | category_name |
| add_to_cart | ✅ | ✅ | product_id, price |
| checkout | ✅ | ✅ | value, items |
| purchase | ✅ | ✅ | order_id, currency, items |
After giving a preview from the GTM Browser Server-side, we see that all tags have fired successfully.
Custom Domain Setup with Stape.io to enhance tracking accuracy and ensure compliance with privacy regulations.
