🛠️ Changelog

Version 1.05 – 7 th April 2025

✨ New Features:

• Automatic Cookie Consent Handling (with Fallback)
  The script now respects Shopify’s customer privacy API. If a consent app is installed, it will only run tracking after marketing consent is given.
  ✅ If no cookie banner or consent app is present, the script automatically runs, ensuring tracking still works out of the box.

🧠 Improvements:

• Universal Compatibility
  Works seamlessly with or without cookie consent apps — no extra setup needed.
• Console Warnings
  Helpful messages added to the browser console when the privacy API is not detected or consent is denied — makes troubleshooting easier for store owners.

🔐 Compliance Ready (but Flexible)
For stores in regions like the EU/UK/CA, tracking respects privacy laws by default. For others, no setup changes are needed — just paste and go.

Version 1.04 – 6th April 2025

✨ New Features:

• begin_checkout event added
  Tracks when a user starts the checkout process, improving funnel visibility and audience targeting.
• remove_from_cart event added
  Helps build audiences based on cart abandonment behavior.
• customer_login and customer_account_created events added
  Enables retargeting or exclusion of logged-in users and new customer sign-ups for more refined remarketing lists.

🧠 Improvements:

• Deduplication logic for purchase events
  Prevents duplicate conversions being sent to Google Ads during multi-trigger scenarios.
• Null/undefined safety added to all event handlers
  Prevents errors when product or variant data is missing—ensures reliable performance even with unusual product setups (e.g. bundles, custom apps).
• Standardized product ID generation
  All event handlers now use a centralized getItemId() function for consistent and clean tracking across all product ID formats (shopify, sku, variant_id, parent_id).
• Inline logic for begin_checkout event
  No longer depends on shared utility functions, keeping things fast and lightweight.
• Conversion callback (event_callback) added to purchase
  Ensures Google Ads recognizes the conversion even during quick page transitions or redirects.

🧼 Refactoring:

• Cleaner code structure and reduced duplication.
• All item processing logic now uses Array.map().filter() for safe and accurate payload creation.

Version 1.02 – 17th June 2024

First itteration of the Google Ads remarketing pixel code for Shopify customer events.
