Fix Meta Ads Conversion Tracking for BookingLayer + GA4 (Pixel Audit + Conversions API Setup)

Fix Meta Ads Conversion Tracking for BookingLayer + GA4 (Pixel Audit + Conversions API Setup) We run Meta (Facebook/Instagram) ads driving traffic to a booking site built on BookingLayer, and our reported conversions in Google Analytics 4 are significantly lower than what we'd expect given ad spend We need an experienced tracking/analytics specialist to diagnose and fix the gap What we need: 1 Audit our current setup — Review our Meta Pixel implementation in BookingLayer (Sales, Booking Engine, Tracking), our GA4 property, and UTM tagging on our Meta ads to identify why paid social conversions are under-reporting 2 Fix GA4 attribution — Ensure Meta traffic is correctly UTM-tagged and showing up under the right channel/source-medium in GA4 (not falling into Direct or Organic Social) 3 Set up Meta Conversions API (CAPI) — Since BookingLayer only supports the browser-side Pixel natively, we need server-side conversion tracking built using BookingLayer's REST API and webhooks to send Purchase (and ideally InitiateCheckout/Lead) events directly to Meta, with proper event deduplication against the existing Pixel 4 Verify and document — Confirm events fire correctly (Pixel Helper, Meta Test Events, GA4 DebugView) and provide brief documentation of what was changed and how to maintain it Requirements: - Proven experience with Meta Pixel and Conversions API (CAPI) implementations - Experience with GA4 setup, UTM tagging, and source/medium troubleshooting - Comfortable working with REST APIs and webhooks (BookingLayer API docs available at docs bookinglayer com) - Bonus: prior experience specifically with BookingLayer, or similar booking-engine/travel platforms Deliverables: - Working Meta Pixel and CAPI setup with deduplication - Corrected UTM tagging across active Meta campaigns - GA4 reporting showing accurate Meta-attributed conversions - Short write-up/documentation of the fix To apply, please include: - A similar project you've completed (CAPI setup or GA4/Meta tracking audit), with results if possible - Your estimated timeline and budget for this scope
