Openpixly installs the official ChatGPT Ads Measurement Pixel on every
page and sends the standard conversion events for you:

page_viewed on every page.
contents_viewed on WooCommerce product pages.
items_added on add to cart (classic, AJAX and block/Store API carts).
checkout_started on the checkout page.
order_created on the order-received page, and again from the server
through the Conversions API with the same event ID so OpenAI deduplicates it.
registration_completed when a user or customer registers.

Amounts are sent as integers in the currency’s ISO 4217 minor unit, customer
identifiers are normalized and SHA-256 hashed on the server before they reach
the browser, and a <noscript> image tag covers visitors without JavaScript.

Meta (Facebook & Instagram) pixel

Enable the Meta provider and enter your Pixel ID to send the same events to
Meta: PageView, ViewContent, AddToCart, InitiateCheckout, Purchase
and CompleteRegistration, with content_ids / contents that match the
Meta catalog feed. Advanced matching data is normalized and SHA-256 hashed on
the server. With a Conversions API access token, Purchase is also sent from
the server with the same event ID, the _fbp / _fbc cookies captured at
checkout, and the customer’s IP address and user agent, so Meta deduplicates
browser and server events. Each provider has its own “Track WooCommerce
events” switch.

Consent

Choose “Require consent first” to initialize the pixel with consent set to
false. Grant consent from your cookie banner with window.openPixel.grantConsent();
the WP Consent API “marketing” category is detected automatically.

Conversions API

Enable it and paste the API key from the Conversions tab of Ads Manager (for
Meta: the access token from Events Manager). Orders are delivered
asynchronously with retries and logged under WooCommerce > Status > Logs
(source: openpixly). The OpenAI “Send test event” button validates your
credentials without recording anything; the Meta one sends the event with
your test event code so it only shows under Events Manager > Test events.

Product feed for ChatGPT Ads

The Product feed tab builds a catalog file from your WooCommerce products in
the OpenAI product feed format (or the Google-compatible profile) as CSV, TSV
or JSONL: one row per simple product or variation, with group_id and
variant_dict for variants, prices as “79.99 USD”, availability, images,
brand, category, GTIN/MPN and is_ads_eligible. The file is rebuilt on a
schedule and served at a private tokenized URL you can hand to OpenAI, or
downloaded for upload to the SFTP location shown in Ads Manager > Feeds.

Meta catalog feed

Switch on “Also build a Meta catalog feed” and the same build writes a second
CSV in Meta’s catalog format (id, title, description, availability, condition,
price, link, image_link, brand, sale_price, item_group_id, …), served at its
own private URL. Paste it in Commerce Manager > Catalog > Data sources > Data
feed > Scheduled feed. Item ids equal the pixel’s content_ids, which is what
Advantage+ catalog ads need.

Extensible

The plugin is a small pixel manager: integrations emit normalized events on
a bus and each provider maps them to its own API. Additional providers
(Google Ads, TikTok, …) can be registered with the
openpixel_pixel_providers filter.

External services

This plugin is an integration with OpenAI’s ChatGPT Ads measurement services and, optionally, Meta’s (Facebook & Instagram) measurement services. Openpixly is developed by Unbelievable Digital and is not affiliated with or endorsed by OpenAI or Meta. Nothing is loaded or sent to a service until a site administrator enables that provider and enters its Pixel ID.

OpenAI Measurement Pixel (browser SDK) — https://bzrcdn.openai.com/sdk/oaiq.min.js and https://bzrcdn.openai.com/pixel-config/ — loaded on every front-end page while the provider is enabled, to measure ad conversions. The SDK sends measurement events to https://bzr.openai.com: page views (page id and title), product views, add-to-cart, checkout and purchase events (WooCommerce product ids, names, quantities and amounts), and registrations. The SDK reads and sets first-party cookies (__oppref, __obref) for click attribution and may collect the visitor’s IP address and user agent as part of the request. When “Send hashed customer data” is on, the plugin also passes SHA-256 hashes of the logged-in user’s or the order’s billing email, phone, first and last name, and the plain-text billing country, city, region and postal code, to improve conversion matching. Raw email, phone or names are never sent.

OpenAI image tag (no-JavaScript fallback) — https://bzr.openai.com/v1/sdk/events — when enabled, a 1×1 image records a page view for visitors without JavaScript. It carries only the Pixel ID and event name.

OpenAI Conversions API (server-to-server) — https://bzr.openai.com/v1/events — only when enabled with your Conversions API key. When an order is paid, the plugin sends the order id, total, currency and line items (product ids, names, quantities, amounts, variant attributes), the SHA-256 hashed billing email, phone, first and last name, the billing country, city, region and postal code, the customer’s IP address and user agent, and the attribution cookie values captured at checkout. The admin “Send test event” button sends a synthetic event with validate_only set, which OpenAI validates but does not store.

The product feed feature does not contact OpenAI or Meta by itself; it generates files on your server that you choose to give to them.

Meta Pixel (browser SDK) — https://connect.facebook.net/en_US/fbevents.js — loaded on every front-end page while the Meta provider is enabled, to measure ad conversions. The SDK sends events to https://www.facebook.com/tr: page views, product views, add-to-cart, checkout and purchase events (WooCommerce product ids, names, quantities and amounts), and registrations. The SDK reads and sets first-party cookies (_fbp, _fbc) and may collect the visitor’s IP address and user agent as part of the request. When “Send hashed customer data” is on, the plugin also passes SHA-256 hashes of the logged-in user’s or the order’s billing email, phone, first and last name, city, region, postal code, country and customer id (Meta advanced matching). Raw values are never sent.

Meta image tag (no-JavaScript fallback) — https://www.facebook.com/tr — when enabled, a 1×1 image records a PageView for visitors without JavaScript. It carries only the Pixel ID and event name.

Meta Conversions API (server-to-server) — https://graph.facebook.com/ — only when enabled with your access token. When an order is paid, the plugin sends the order id, total, currency and line items (product ids, quantities, unit prices), the SHA-256 hashed billing email, phone, first and last name, city, region, postal code, country and customer id, the customer’s IP address and user agent, and the _fbp / _fbc cookie values captured at checkout. The admin “Send test event” button sends a synthetic event carrying your test event code, which Meta shows under Test events and does not count as a conversion.

Consent. Measurement is opt-in for the site owner (disabled until configured) and administrators are excluded by default. To make it opt-in for visitors, choose “Require consent first” on each provider: the pixel then starts with consent revoked (oaiq("consent", false) / fbq("consent", "revoke")) and only measures after your cookie banner calls window.openPixel.grantConsent() or the WP Consent API reports the “marketing” category as allowed. Server-side Conversions API events are sent for paid orders whenever that option is enabled; leave it off if your legal basis requires browser consent for them too. Disclose the pixels you use in your site’s privacy policy.
