README

Lightweight tracking pixel manager for WordPress, with ChatGPT Ads conversion tracking from the browser and the server.

What it does

Loads tracking pixels from the major ad networks and dispatches the standard ecommerce / conversion events for them, in the browser and from your server. No upsell, no tracking, no bloat.

ChatGPT Ads conversion tracking

Browser pixel (oaiq) and Conversions API (server-side), deduplicated with a shared event ID
WooCommerce — contents_viewed, items_added, checkout_started, order_created (once per order; amounts in ISO 4217 minor units)
Leads and signups — form submissions as lead_created, new accounts as registration_completed; page views as page_viewed
Custom events — your own events as custom with a valid custom_event_name
Consent — marketing category via LW Cookie, for the pixel and the server-side events
Optional SHA-256 hashed advanced matching, debug mode, validate_only connection test
The API key can live in wp-config.php: define( 'LW_PIXEL_CHATGPT_API_KEY', '...' );

Admin

A React settings screen with a side navigation; the Quick search field at the top of the sidebar (Cmd/Ctrl+K) finds any section, card or setting by name and opens it.

Supported pixels

ChatGPT Ads — oaiq measurement pixel + Conversions API server-side
Meta (Facebook) Pixel — fbq browser pixel + Conversion API server-side (Advanced Matching, External ID, Order Enrich)
Google Analytics 4 — gtag.js + Measurement Protocol server-side
Google Ads — conversion tracking
Google Tag Manager — container + dataLayer, optionally in the GA4 ecommerce format (view_item, add_to_cart, begin_checkout, purchase)
TikTok Pixel — ttq
Pinterest Tag — pintrk + Conversions API server-side
Microsoft Bing UET — uetq
Reddit Pixel — rdt
Snapchat Pixel — snaptr
X (Twitter) Pixel — twq
Barion Pixel — bp (WooCommerce events in Barion's format; the fraud-prevention base pixel can load before consent, the shop events wait for marketing consent, the banner answer is sent as grantConsent / rejectConsent; the Barion Payment Gateway's own pixel is switched off)

Supported events

PageView (auto, every page)
ViewContent — single posts/pages and WooCommerce products
Search — search results pages
Lead / Contact — form submissions
AddToCart, InitiateCheckout, AddPaymentInfo, Purchase, ViewCart, ViewCategory — WooCommerce
Login, Signup (CompleteRegistration), Comment — server-side, replayed on the next page load
Scroll, TimeOnPage, Download — auto-tracked frontend events with configurable thresholds
Contact (tel:/mailto: link clicks), Lead (thank-you page match) — auto-tracked, off by default
Custom events — define your own with the editor (page_load / click / scroll / time triggers, URL patterns)

Server-side events

Meta Conversion API — every standard event (PageView, ViewContent, Search, Lead, Contact, AddToCart, InitiateCheckout, AddPaymentInfo, Purchase, CompleteRegistration)
ChatGPT Ads Conversions API — the same events as the ChatGPT Ads pixel
Pinterest Conversions API — purchase (checkout, once per order), add to cart, page visit, category view, lead, search and signup; ad account ID + conversion access token (or LW_PIXEL_PINTEREST_TOKEN in wp-config.php), the _epik click ID, optional hashed advanced matching, test mode (?test=true) and a connection test. A started checkout is not sent to Pinterest: its checkout event is the completed purchase.
GA4 Measurement Protocol — the purchase; all events when GA4 is loaded by something else (e.g. Tag Manager), since GA4 does not deduplicate against gtag.js
Deduplication — the browser and server copies share one event ID (Meta eventID, GA4 event_id parameter, ChatGPT Ads and Pinterest event_id); a purchase uses an order-based ID and is sent once per order and provider
Consent — each provider's server copy follows the visitor's consent for that pixel
Non-blocking — sent after the response is flushed, or in the background via Action Scheduler; nothing sent is logged
Cache-safe — page-level events go server-side only on pages that a page cache cannot share between visitors

Integrations

Compliance

Medical traffic mode — strips PII from event payloads and from server-side user data (Meta CAPI, ChatGPT Ads, Pinterest, GA4 MP) (HIPAA-friendly)
Limited Data Use (LDU) — adds Meta data_processing_options for California / CCPA (auto-resolve or force California) and marks Pinterest Conversions API events with opt_out_type: LDP

Migration

Built-in settings importer under LW Plugins → Pixel → Tools: it detects a supported previous pixel plugin, shows a preview diff and imports in one click (also available as wp lw-pixel migrate).

Installation

composer require lwplugins/lw-pixel

Or download a release ZIP from the GitHub releases page.

Configuration

After activation, go to LW Plugins → Pixel and add your pixel IDs. Each provider has its own settings, including its server-side options.
