UniPixel: Server-side Event Tracking & Consent for Meta, TikTok and Google

Description

UniPixel brings next-level event tracking to WordPress with full client- and server-side support for Meta, TikTok and Google.
No need for extra apps, external cloud servers, or separate custom domains for server-side sending. Easy install to your existing WordPress website.
It solves the growing gaps caused by browser restrictions, ad blockers, and cookie limits — ensuring your conversion data stays accurate, complete, and privacy-safe.

• Fine-tuned control over client-side and server-side event sending for every platform.
• Works with Meta Conversion API, «TikTok Events API» and Google Server-Side Tagging.
• Tracks standard WooCommerce events (ViewContent, AddToCart, InitiateCheckout, Purchase) with full order and product data.
• Create and manage your own custom events for clicks, views, and interactions.
• Automatic deduplication keeps matching client/server events counted only once.
• Built-in consent banner integrates with your site’s privacy framework to control when events are allowed to send.
• Live event viewer for testing, plus optional database logging for full event history.
• Simple setup with clear layouts, recommended defaults, and inline help.

Why Use UniPixel

Modern tracking needs more than browser pixels.
UniPixel sends verified conversion events directly from your own server to Meta and Google — keeping data flowing even when scripts or cookies are blocked.
No complex cloud setup or additioal hosting, easy installation, be setup in mintues.
Client-side tracking still runs for richer, contextual insights, while server-side delivery ensures reliability and compliance.
Everything is managed inside WordPress, giving you transparent control over how events send, when consent applies, and how data is logged.

The result: more complete measurement, better ad platform optimisation, and a future-proof tracking setup for your store or website.

What if I already have Meta or Google tracking installed?

If your site already includes tracking via another plugin or manually, select «Pixel Already Included» in UniPixel settings. This prevents duplicate tracking scripts but still allows UniPixel to send custom events.

How does server-side event tracking work?

UniPixel supports both client-side and server-side event tracking:
– Client-side events are sent directly from the browser.
– Server-side events use API calls to prevent ad blockers from blocking conversions.

To enable server-side tracking for Meta, enter your Access Token.
For Google, enter your API Secret.

How does UniPixel prevent duplicate events?

UniPixel uses event deduplication by assigning a unique event ID to each event. This ensures that events sent via both client-side and server-side are not counted twice.

Tips

Deduplication

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.

• Meta (Facebook / Instagram) – Uses event_id to match Pixel and Conversion API events so they count once.
• Google (GA4 / Ads) – Uses shared client_id and session_id values for client/server matching. Works automatically for both client-first and server-first setups.
• TikTok – Uses shared event IDs across Pixel and Events API for seamless deduplication.

No extra setup is required — UniPixel handles ID creation and matching automatically.
