Meta Conversions API vs Google Enhanced Conversions

1. The Cross-Platform Tracking Fragmentation

Every major ad network developed its own proprietary server-side tracking standard: Meta created the Conversions API (CAPI), while Google introduced Enhanced Conversions (for Web and Leads).

While both aim to restore post-cookie attribution, their schemas, hashing rules, and API endpoints are completely different. Managing separate tracking implementations for Meta, Google, and TikTok leads to tag bloat, code maintenance headaches, and inconsistent attribution numbers.

2. Comparative Analysis: Standard Tracking vs CAPI Control

The table below outlines the architectural and financial differences between passive conversion tracking and active signal governance:

3. Unified Single-Payload Multi-Network Dispatch

CAPI Control ingests a single standardized conversion payload from your store and maps it dynamically into both Meta and Google schemas simultaneously:

// Unified Event Transformation in CAPI Control
export async function dispatchUnifiedConversion(order) {
  // Concurrently format and dispatch to both Meta and Google
  await Promise.all([
    sendToMetaCAPI({
      event_name: "Purchase",
      event_id: order.id,
      user_data: { em: [sha256(order.email)], fbc: order.fbc },
      custom_data: { value: order.profitValue, currency: "USD" }
    }),
    sendToGoogleEnhancedConversions({
      conversion_action: "customers/123/conversionActions/456",
      gclid: order.gclid,
      user_identifiers: [{ hashed_email: sha256(order.email) }],
      conversion_value: order.profitValue
    })
  ]);
}
