axitrace

AxiTrace for WooCommerce connects your store to the AxiTrace server-side tracking platform at <a href="https://axitrace.com/" rel="nofollow ugc">axitrace.com</a>. Every purchase, add-to-cart, and begin-checkout event is captured on the server and forwarded to your ad platforms — reaching customers that browser-based pixels miss entirely.
Why server-side tracking?
Browser pixels can be blocked by ad blockers, restricted by iOS Intelligent Tracking Prevention, and refused via cookie consent banners. Server-side events travel directly from your WooCommerce server to Facebook CAPI, TikTok Events API, Google Ads, and Google Analytics 4, so conversions are still recorded when the browser pixel cannot fire.
Deduplication so you never double-count
AxiTrace generates a deterministic UUID v5 event ID for every WooCommerce order. The same event ID is attached to both the browser-side purchase pixel fire and the server-side purchase event. Facebook CAPI, TikTok Events API, and Google Ads use that shared event ID to deduplicate automatically — each conversion is counted exactly once, regardless of how many times the confirmation page loads or how many pixels fire.
Server-side AddToCart events
AxiTrace sends AddToCart events server-side, triggered by the WooCommerce <code>woocommerce_add_to_cart</code> hook. This records add-to-cart activity from the server, so the event is captured even when the browser-side pixel is blocked or restricted.
Asynchronous by design — checkout never blocks
All server-side event transmissions are dispatched via WooCommerce Action Scheduler. The HTTP request to AxiTrace’s ingestion API happens in a background job, decoupled from the order placement flow. Checkout latency is unaffected even if the AxiTrace API is momentarily slow or unavailable.
Platform coverage
One plugin. One workspace key. AxiTrace routes your events to whichever ad platforms you connect in your dashboard:
<ul>
<li>Facebook / Meta — Conversions API (CAPI)</li>
<li>TikTok — Events API (server-side)</li>
<li>Google Ads — Offline Conversion Upload (GCLID-based attribution)</li>
<li>Google Analytics 4 — Measurement Protocol</li>
</ul>
HPOS and Cart/Checkout Blocks compatible
AxiTrace for WooCommerce declares compatibility with WooCommerce High-Performance Order Storage (HPOS) and the modern Cart/Checkout Blocks, so it works correctly on stores that have migrated away from legacy shortcode-based checkout.
WP Consent API support
The plugin detects the <a href="https://wordpress.org/plugins/wp-consent-api/" rel="ugc">WP Consent API</a> and checks the visitor’s consent level before firing events. When no consent framework is present, the plugin fires freely (opt-out model). When a framework is present, the plugin respects the consent status for the <code>statistics</code> and <code>marketing</code> categories. This gives your store a ready compliance path without requiring you to build custom integration.
GDPR personal-data tools built in
AxiTrace registers a WordPress personal-data exporter and eraser (<code>wp_privacy_personal_data_exporters</code> / <code>wp_privacy_personal_data_erasers</code>), enabling your store to fulfill GDPR deletion requests directly from the WordPress Tools > Erase Personal Data screen.
Privacy first
Customer email addresses and phone numbers are transmitted in plain text to AxiTrace’s ingestion API at <code>stat.axitrace.com</code> and are SHA-256 hashed inside AxiTrace before being forwarded to any ad platform. No raw PII leaves the AxiTrace platform. See our Privacy Policy at <a href="https://axitrace.com/privacy/" rel="nofollow ugc">axitrace.com/privacy/</a> and the <code>== External Services ==</code> section below for the complete disclosure.
Free plugin. Paid plans for volume.
The plugin itself is free and open source (GPL v2 or later). An AxiTrace account at <a href="https://axitrace.com/" rel="nofollow ugc">axitrace.com</a> is required. Free workspaces are available. Paid plans unlock higher event volumes, longer data retention, and priority support — see <a href="https://axitrace.com/" rel="nofollow ugc">axitrace.com</a> for current pricing.

<h3>External Services</h3>
This plugin connects to stat.axitrace.com — the AxiTrace event-ingestion API.
<ul>
<li>Service: AxiTrace conversion tracking SaaS.</li>
<li>Endpoint: <code>https://stat.axitrace.com/woocommerce/pixel</code> (POST).</li>
<li>When data is sent: on page views (cart, product, checkout, thank-you), add-to-cart events, begin-checkout events, and order placement / payment completion.</li>
<li>Data transmitted: order ID, plain-text billing email (hashed downstream by AxiTrace), billing phone, billing city/country/zip, order total + currency, line items (SKU, name, quantity, price), user agent, IP address, AxiTrace session/user identifiers, click-attribution cookies (fbc, fbp, gclid, ttclid, msclkid, twclid, epik, li_fat_id, sccid, rdt_cid), UTM parameters, page URL/referrer/title.</li>
<li>Why: to forward the conversion to Facebook CAPI, TikTok Events API, Google Ads, GA4, and other ad platforms configured in your AxiTrace workspace.</li>

</ul>
Optional first-party tracking domain
You may optionally configure a custom first-party subdomain under WooCommerce → Settings → Integrations → AxiTrace → “First-party tracking domain”. When set to e.g. <code>metrics.your-store.com</code> (which you set up in your AxiTrace workspace and verify via CNAME to <code>stat.axitrace.com</code>), the SDK and ingestion endpoint load from your own domain instead of stat.axitrace.com. The data transmitted, the endpoint path (<code>/woocommerce/pixel</code>), and the recipient (AxiTrace) remain identical — only the hostname changes. This is purely a delivery optimization that helps bypass client-side blocking; no third-party service is added.
When this field is empty, the plugin uses the default <code>stat.axitrace.com</code> endpoint described above.
Auto-detect lookup endpoint
When the merchant clicks the “Detect from AxiTrace” button on the settings page, the plugin makes a single server-to-server GET request to <code>https://axitrace.com/api/public/workspace/tracking-domain?key={public_key}</code> (AxiTrace admin host — separate from the ingestion host <code>stat.axitrace.com</code>) to look up the default verified domain registered for that workspace. The request contains only the merchant’s own workspace public key (already exposed in every browser event); no customer or visitor data is sent.

AxiTrace for WooCommerce

Server-side conversion tracking for WooCommerce — Facebook CAPI, TikTok Events API, Google Ads, and GA4 from one plugin.

Buildio

Ad blockers, iOS privacy changes and cookie restrictions mean your browser-based tracking pixel is only reporting a fraction of your actual conversions. Your ads cannot optimise on data they never receive.
UniPixel fixes this by sending conversion events directly from your WordPress server to Meta, Pinterest, TikTok, Google and Microsoft — bypassing the browser entirely. No external cloud hosting, no GTM server container. Install, paste your credentials, and server-side tracking is live.
<h3>What It Does</h3>
<ul>
<li>Meta Conversion API (CAPI) — server-side and client-side event sending with full deduplication.</li>
<li>Pinterest Conversions API — server-side and client-side tracking with full deduplication.</li>
<li>TikTok Events API — server-side and client-side tracking with automatic deduplication.</li>
<li>GA4 Measurement Protocol — server-side event delivery to Google Analytics and Google Ads.</li>
<li>Microsoft UET & Conversions API — client-side tracking via UET with early support for Microsoft’s Conversions API (CAPI) pilot program. WooCommerce events and custom events supported.</li>
<li>WooCommerce events — ViewContent, AddToCart, InitiateCheckout and Purchase tracked automatically with full product data (names, categories, variants, values).</li>
<li>Custom events — create your own click, view and interaction events for any WordPress page. Not limited to WooCommerce.</li>
<li>Automatic deduplication — each event gets a unique ID shared between client and server, so platforms count it once.</li>
<li>Built-in consent management — fully featured popup with built-in translations for 18 languages, editable wording per language, 5 layout styles (centred card / top or bottom bar / corner card), optional non-blocking mode, and a Reject all button toggle. Or skip the popup entirely and let UniPixel read consent from your existing CMP — supports OneTrust, Cookiebot, Osano, Silktide, Orest Bida, Complianz, CookieYes, Moove GDPR, and CookieAdmin (Softaculous).</li>
<li>Live event testing — real-time console shows events as they fire, with full payload data.</li>
<li>Event logging — optional database storage of every event sent, for debugging and audit.</li>
</ul>
<h3>Why Server-Side Tracking Matters</h3>
Around 43% of internet users run ad blockers. Safari limits cookies to 7 days. iOS App Tracking Transparency reduced reported conversions by 30-40% for many advertisers. When your tracking relies only on a browser pixel, these restrictions silently discard your conversion data.
Server-side tracking sends conversion data directly from your server to the ad platform API. Ad blockers cannot touch it. Cookie limits do not apply. The result: your ad platforms see your real conversions, optimise better, and your ad spend works harder.
<h3>Why UniPixel</h3>
UniPixel sends API calls directly from your own WordPress server. No GTM server container, no external cloud, no routing your data through third-party services.
<ul>
<li>Meta, Pinterest, TikTok, Google and Microsoft — server-side and client-side tracking for all five platforms.</li>
<li>No GTM required — no server container setup, no custom subdomain, no separate hosting.</li>
<li>No external cloud — your data goes from your server to the ad platform. Nothing in between.</li>
<li>Works on any WordPress site — WooCommerce stores get automatic ecommerce event tracking. Non-WooCommerce sites use custom events for lead gen, SaaS, content or anything else.</li>
<li>Five-minute setup — install, enter your Pixel ID and access token, enable the platform. Done.</li>
</ul>
Optional <a href="https://unipixelhq.com/unipixel-docs/advanced-matching-setting-with-unipixel/" rel="nofollow ugc">Advanced Matching</a> sends hashed user data (email, phone, address) alongside events to help platforms improve Event Match Quality.
<h3>Tips</h3>
<h4>Deduplication</h4>
UniPixel automatically prevents duplicate counting when both client-side and server-side events are enabled.
Each event is assigned a unique event_id when triggered. This same ID is sent to both the browser pixel and the server API, allowing platforms to merge identical events.
<ul>
<li>Meta (Facebook / Instagram) — uses <code>event_id</code> to match Pixel and Conversion API events so they count once.</li>
<li>Pinterest — uses <code>event_id</code> to match Tag and Conversions API events for full deduplication.</li>
<li>TikTok — uses shared event IDs across Pixel and Events API for seamless deduplication.</li>
<li>Google (GA4 / Ads) — uses shared <code>client_id</code> and <code>session_id</code> values for client/server matching. Works automatically for both client-first and server-first setups.</li>
<li>Microsoft (Bing / UET) — uses <code>eventId</code> to match UET tag and Conversions API events for deduplication.</li>
</ul>
No extra setup is required — UniPixel handles ID creation and matching automatically.
