Overview
LayerSync is server-side conversion tracking for WooCommerce. It captures ecommerce events and forwards them through the LayerSync SaaS to nine 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, and X (Twitter).
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.
Why Server-Side Tracking
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 event_id so browser and server halves are deduplicated automatically.
What’s Included
Nine 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. 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 (payment_complete + checkout_order_processed + woocommerce_thankyou) so custom checkouts still fire.
Lead-form auto-detect — Contact Form 7, WPForms, Ninja Forms, Formidable Forms, and WooCommerce checkout forms.
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), sendBeacon on page exit.
Privacy & compliance — per-event consent snapshot, default-denied mode, CMP integration via window.LayerSync.setConsent(), 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).
Free vs Paid Plans
Free includes browser pixels for all 9 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 9 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).

For Developers
LayerSync exposes a JavaScript API, a same-origin REST endpoint, and WordPress hooks for custom event tracking.
JavaScript API:
window.LayerSync.track('lead', {email: '[email protected]', value: 25.00, currency: 'USD'});
window.LayerSync.setConsent({ad_storage: 'granted', ad_user_data: 'granted'});
REST endpoint (same-origin, nonce-protected, survives ad-blockers and corporate firewalls):
POST /wp-json/layersync/v1/events
WordPress filter hooks: layersync_event_payload, layersync_event_before_enqueue, layersync_event_after_delivery, layersync_consent.
Full API documentation: layersynchub.com/docs.
Compatibility
Works alongside Cookiebot, CookieYes, OneTrust, Borlabs Cookie, Complianz, and any CMP that supports a JS consent callback. Compatible with WP Rocket, LiteSpeed Cache, W3 Total Cache, Cloudflare, and other major caching/CDN solutions.

Important Notes:
No automatic data sharing: LayerSync does NOT send any data to ad platforms unless you explicitly enable them in your LayerSync dashboard
Consent-aware: LayerSync respects user consent state via the window.LayerSync.setConsent() API and only fires browser pixels and server events after consent is granted
You control the data: You choose which platforms to enable, what events to track, and what user data to include (emails, phones, etc.)
Required account: This plugin requires a LayerSync account to operate. The plugin alone does not function without API credentials from layersynchub.com.
