LayerSync – Conversion Tracking, Pixel Manager, and Server-Side API vs Pixelavo – Server Side Tracking & Pixel + AI Ads Tools

Overview 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. 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 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 (payment_complete + checkout_order_processed + woocommerce_thankyou) 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 ad_user_data 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 tests/Unit/. 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 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). Compare Plans 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. Getting Started Sign up at layersynchub.com and create your first site.

Facebook Conversions API Facebook Conversions API (formerly known as the Server-Side API) is a tool that allows businesses to send their website or app conversion data directly to Facebook’s servers, bypassing the need for browser-based tracking methods like the Facebook Pixel. Using the Conversions API, businesses can track actions such as purchases, sign-ups, and other valuable events that occur on their website or app. This data can then be used to optimize Facebook advertising campaigns, such as retargeting ads to users who have already taken specific actions on the business’s website or app. Some benefits of using Facebook Conversions API include: Helps improve tracking accuracy: By bypassing the need for browser-based tracking, businesses can ensure that all conversion data is captured accurately, even if a user’s browser settings or ad-blocking software prevent the Facebook Pixel from tracking their actions. Increased privacy: Because the Conversions API sends data directly to Facebook’s servers, businesses can reduce the amount of user data that is shared with third-party trackers, potentially improving user privacy and security. Greater control: The Conversions API allows businesses to track and send custom data points to Facebook, giving them greater flexibility and control over how they track and optimize their advertising campaigns. Helps reduce potential data loss: Because the Conversions API relies on server-to-server communication, rather than browser-based tracking, businesses can reduce the risk of data loss due to issues like browser crashes or network outages. Overall, the Facebook Conversions API can provide businesses with a more accurate, flexible, and privacy-focused way to track and optimize their Facebook advertising campaigns. Need Help?
