GA4 Tracking Setup

Job ID: 40592467

Budget: $250 – $750 AUD

GA4 / GTM Tracking Migration + Server-Side Conversions API Setup (Meta, TikTok) — Hospitality Client

Overview:
We're a marketing agency looking for an experienced tracking/analytics specialist to help migrate and extend our tracking setup for a multi-venue hospitality client. The work is split into two distinct pieces — happy to award to one contractor covering both, or separately if that suits your specialty better.
Task 1: GTM Migration & Cleanup (13 venues)
Our client recently moved reservation platforms (from SevenRooms to ME&U Tables). We need:

Review of the existing SevenRooms GTM implementation and mapping of ME&U's available booking events/data
Updated GTM variables, triggers and tags so booking revenue, headcount, checkout steps and reservation data track correctly into GA4 and other platforms
Fallback handling for missing values
Testing via GTM Preview mode across multiple booking scenarios
Publishing to production with post-deployment verification
A cleanup of the container — removing obsolete SevenRooms tags, old Universal Analytics tags, and outdated SEO schema markup, with dependency checks so nothing live breaks

Task 2: Offline Revenue Tracking via Webhook (4 venues)
Push offline/POS revenue data into GA4, Meta and TikTok for accurate ROAS reporting. Data flow: booking platform captures attribution/click IDs, joins to POS/reservation data, sends via webhook to our existing tracking server, which then pushes events to each ad platform. Requires:

Signed webhook endpoint configuration and verification
Webhook receiver build on our existing tracking server, with payload parsing
GA4 Measurement Protocol integration (event mapping, logging, error handling, retry logic, tested in DebugView)
Meta Conversions API integration (same requirements, tested in Meta Test Events)
TikTok Conversions API integration (same requirements)
Full testing and production deployment for all three

What we're looking for:

Demonstrated experience with GA4 Measurement Protocol and/or Meta/TikTok Conversions API (not just standard GA4/GTM setup) — please reference a past project if possible
Comfort working with an existing server/webhook infrastructure rather than building from scratch
Australia-based or Australia-friendly working hours preferred, given this touches a live client's revenue data
Clear communication and ability to document changes (especially for the GTM cleanup)

Ideal Skills and Experience:
- Expertise in Google Analytics 4 (GA4)
- Experience with Measurement Protocol and Conversions API
- Ability to define and set up tracking events
- Familiarity with website analytics and user action tracking
