# Meta Ads Integration

## Overview

Meta (Facebook/Instagram) is the dominant paid social channel for ecommerce, but reliable attribution requires pairing the browser-based Meta Pixel with server-side Conversions API (CAPI). Post-iOS 14, browser signals alone under-report 30–60% of conversions; CAPI restores signal fidelity by sending purchase events directly from your server. For Shopify, WooCommerce, and BigCommerce, official integrations handle both Pixel and CAPI automatically — no custom code required. Custom code only belongs in the Custom/Headless section.

## When to Use This Skill

- When setting up Meta advertising for a new ecommerce store
- When conversion data in Ads Manager looks under-reported after iOS 14 rollout
- When launching Dynamic Product Ads (DPA) and needing catalog feed sync
- When ROAS is declining and you need to restore the signal quality Meta's algorithm relies on
- When adding retargeting audiences based on product viewers and add-to-cart events

## Core Instructions

### Step 1: Choose your integration approach

| Platform | Recommended Method | CAPI Support | Catalog Sync |
|----------|--------------------|-------------|-------------|
| **Shopify** | Native Meta Sales Channel | Yes (built-in) | Yes (automatic) |
| **WooCommerce** | Facebook for WooCommerce plugin | Yes (built-in) | Yes (automatic) |
| **BigCommerce** | Meta channel in Channel Manager | Yes (built-in) | Yes (automatic) |
| **Custom / Headless** | Meta Pixel + facebook-nodejs-business-sdk | Manual CAPI implementation | Manual feed generation |

All three major platforms have official Meta integrations that install both the Pixel and CAPI in a single setup — use these rather than manually pasting Pixel code.

### Step 2: Connect your platform to Meta

---

#### Shopify

1. Go to **Shopify Admin → Sales Channels → + → Facebook & Instagram**
2. Install the Facebook & Instagram sales channel
3. Connect your Meta Business Manager account and select your Facebook Page and Ad Account
4. Under **Data Sharing**, select **Maximum** — this enables server-side CAPI in addition to the browser Pixel
5. Shopify automatically:
   - Installs the Meta Pixel on all pages
   - Fires ViewContent, AddToCart, InitiateCheckout, and Purchase events
   - Sends the same events via CAPI from Shopify's servers (deduplication handled automatically)
   - Syncs your product catalog to Meta Commerce Manager for Dynamic Product Ads
6. Go to **Facebook & Instagram → Overview** to verify pixel connection status
7. In **Meta Events Manager → Data Sources → [Your Pixel]**: check Event Match Quality (EMQ) score — aim for 7+/10

#### WooCommerce

1. Install **Facebook for WooCommerce** (free, official Meta plugin) from the WordPress plugin directory
2. Go to **WooCommerce → Facebook → Get Started** and connect your Meta Business Manager account
3. Under **Facebook Connection → Data Sharing Level**: select **Maximum**
4. The plugin installs the Meta Pixel across all pages and fires standard events automatically
5. CAPI is enabled automatically under the Maximum data sharing setting
6. Go to **WooCommerce → Facebook → Product Sync** to trigger an initial product catalog sync to Meta Commerce Manager
7. Verify catalog sync status in **Meta Commerce Manager → Catalog → Data Sources**
