Layersync Conversion Tracking

<h4>Overview</h4>
LayerSync is server-side conversion tracking for WooCommerce. It captures ecommerce events and forwards them through the LayerSync SaaS to ten ad and analytics platforms via their server-side APIs — Meta (Conversions API), Google Analytics 4 (Measurement Protocol), Google Ads (Enhanced Conversions), TikTok (Events API), Pinterest, Snapchat, LinkedIn, Reddit, X (Twitter), and Microsoft Ads (Bing UET).
Configuration lives in the LayerSync dashboard, so there’s no Google Tag Manager server container, no custom tracking subdomain, no external hosting to manage. The plugin handles WooCommerce; LayerSync handles per-platform delivery.
<h4>Why Server-Side Tracking</h4>
Browser pixels are increasingly blocked by ad-blockers and degraded by Safari/iOS tracking-prevention. Sending the same events server-to-server restores conversion data your ad platforms use to optimize. LayerSync ships WooCommerce events over HMAC-signed HTTPS to the LayerSync hub, which calls each platform’s CAPI with a shared <code>event_id</code> so browser and server halves are deduplicated automatically.
<h4>What’s Included</h4>
Ten ad platforms, one plugin — Meta CAPI, GA4 MP, Google Ads Enhanced Conversions, TikTok Events API, Pinterest CAPI, Snapchat CAPI, LinkedIn CAPI, Reddit CAPI, X CAPI, Microsoft Ads (Bing UET). Browser pixels + server-side CAPI for all of them, with automatic deduplication.
WooCommerce funnel coverage — view item, add to cart, view cart, begin checkout, add payment info, purchase, refund. HPOS-compatible. Triple-fallback purchase capture (<code>payment_complete</code> + <code>checkout_order_processed</code> + <code>woocommerce_thankyou</code>) so custom checkouts still fire.
Lead-form auto-detect — eight form libraries: Contact Form 7, WPForms, Ninja Forms, Formidable Forms, Gravity Forms, Fluent Forms, Elementor Pro Forms, Forminator — plus WooCommerce checkout forms.
Consent & CMP auto-detect — bridges WP Consent API and auto-detects eight CMPs: Complianz, Cookiebot, CookieYes, Borlabs Cookie, iubenda, OneTrust, GDPR Cookie Compliance (Moove), Termly. Strips PII automatically when <code>ad_user_data</code> is denied.
Action Scheduler-backed queue — per-row dispatch via Action Scheduler with WP-Cron fallback. Configurable retention (default 30 days), priority lanes (purchases never evicted), dead-letter UI with operator Replay.
Historical backfill — replay up to 365 days of WooCommerce orders to LayerSync after install or after an outage. Dry-run mode shows what will be queued before any event ships.
Bot & proxy intelligence — multi-signal scoring (datacenter IPs, Apple Private Relay, UA heuristics, velocity, repeated event IDs). Daily-refreshed CIDR list for fresh detection between releases. Operator safe-list overrides.
International phone normalization — 50+ country codes with E.164 canonicalization, dummy-number rejection, and platform-specific hash forms (digits-only for Meta, E.164 for TikTok/Snapchat/Pinterest).
508+ automated tests — PHPUnit coverage on identity, queue retry, encryption, bot scoring, CMP detection, and form adapters. Audit the suite at <code>tests/Unit/</code>.
Browser-side recovery engine — save-first localStorage queue, priority-aware overflow (purchases never dropped), cross-tab serialization, exponential backoff with jitter, multi-day retention (up to 30 days for purchases), <code>sendBeacon</code> on page exit.
Privacy & compliance — per-event consent snapshot, default-denied mode, CMP integration via <code>window.LayerSync.setConsent()</code>, SHA-256 PII hashing, IP anonymization, GDPR / UK ICO / CCPA-aware (Meta Limited Data Use, Do-Not-Sell drop mode).
Operational visibility (via the LayerSync hub) — real-time event status, per-platform delivery success rates, anomaly detection, Slack/PagerDuty/email digest alerts (paid plans).
<h4>Free vs Paid Plans</h4>
Free includes browser pixels for all 10 platforms, server-side CAPI to one platform of your choice, 1 site, 1 team seat, 10,000 events/month, WooCommerce + lead-form auto-tracking, event quality scoring, real-time event log.
Paid plans add: server-side CAPI to all 10 platforms, higher event quotas, multiple sites, team seats, Slack/PagerDuty alerts, anomaly detection, audience builder, ROI dashboard, user journeys, customer profiles, automatic conversion recovery, custom event definitions, white-label (enterprise), custom ingest domain (enterprise).

<h4>For Developers</h4>
LayerSync exposes a JavaScript API, a same-origin REST endpoint, and WordPress hooks for custom event tracking.
JavaScript API:
<pre><code>window.LayerSync.track('lead', {email: 'user@example.com', value: 25.00, currency: 'USD'});
window.LayerSync.setConsent({ad_storage: 'granted', ad_user_data: 'granted'});
</code></pre>
REST endpoint (same-origin, nonce-protected, survives ad-blockers and corporate firewalls):
<pre><code>POST /wp-json/layersync/v1/events
</code></pre>
WordPress filter hooks: <code>layersync_event_payload</code>, <code>layersync_event_before_enqueue</code>, <code>layersync_event_after_delivery</code>, <code>layersync_consent</code>.

TRACK CONVERSION ON YOUR E-COMMERCE PLUGIN 
 When it comes to track conversions on a WordPress page it’s easy… but if it’s a “dynamic thank you page” is a big problem.
 Tracking Code Manager plugin DETECT AUTOMATICALLY your e-commerce plugin (WooCommerce, Easy Digital Downloads or WP eCommerce) and let you put the conversion pixels every time someone completes a sale on your store. 
 In addition you also have the ability to track a single product at time 😉 
 <a href="https://wordpress.org/plugins/tracking-code-manager/screenshots/" rel="ugc">Check some screenshots here.</a>
</blockquote>
<h4>THE REAL PROBLEM</h4>
Since almost every service requires some sort of tracking, update, javascript update or other customization – you can make it extremely simply with this plugin – the fast Tracking Code Manager plugin.
<h4>FORGET THE UPDATING PROBLEM</h4>
Its very easy to break your site! Putting the tracking code directly in the theme files, you risk to lose important trackings or external service integrations when it will be updated. We have all been there!
With Tracking Code Manager you can forget about this problem also if you will change your theme in the future. Because we are external to the theme – you have reduced your risk between updates to WordPress and any themes or plugin updates.
