Facebook Pixel Tag for Google Tag Manager (Web)

The Facebook Pixel is a snippet of JavaScript code that allows you to track visitor activity on your website. It works by loading a small library of functions which you can use whenever a site visitor takes an action (called an event) that you want to track (called a conversion). Learn More.

This is a Google Tag Manager Community Template Gallery tag for the Facebook Pixel. It lets you configure and deploy the Facebook Pixel directly from a GTM web container without editing site code manually. The template supports:

Standard and custom event tracking
Advanced Matching (customer information parameters)
Enhanced Ecommerce dataLayer integration
Multiple Pixel IDs
Object and custom data properties
Data Processing Options (for CCPA/LDU compliance)
Consent mode
Event ID for server-side deduplication

Installation

In your Google Tag Manager web container, navigate to Templates > Tag Templates > Search Gallery.
Search for Facebook Pixel
Add the template to your workspace.
Create a new tag using the template, enter your Pixel ID(s), and configure the desired events.

For more details, see the template documentation.
