Shopify tracking setup for Google Ads launch

Shopify tracking setup for Google Ads launch. GA4, conversion tracking, iframe booking events (UK healthcare clinic) We're a CQC-registered private clinic in London (Shopify site) launching Google Ads immediately. We need our measurement stack set up and verified end-to-end before we spend. Site: wearenaya.com SCOPE 1. GA4 property connected to Shopify (Google & YouTube channel app or gtag/GTM — your recommendation), with custom events: - generate_lead (form submit) - book_consultation (booking completed — PRIMARY conversion) - phone_click (tel: link taps) 2. Our consultation booking completes inside a third-party embedded widget/iframe (Select&Book and/or Carebit). Bookings made inside it must fire the conversion via postMessage-to-dataLayer, thank-you-page redirect, or the vendor's native integration. You tell us the cleanest approach. 3. Google Ads conversion tracking: link GA4 ↔ Google Ads, import book_consultation as primary conversion, enable Enhanced Conversions. 4. Install call-tracking snippet (we'll supply CallRail/WhatConverts account) with dynamic number insertion. 5. Consent Mode v2 compliant cookie consent on Shopify (built-in Customer Privacy or Pandectes) configured so Ads measurement works for consenting UK users. Job sign-off One real test booking + one test call, both visible as conversions in Google Ads and events in GA4, screen-recorded walkthrough of the setup. Written 1-page handover of what was installed and where. ACCESS PROVIDED: Shopify collaborator access, GA4 admin, Google Ads standard access, booking-widget vendor logins as needed. REQUIREMENTS: proven Shopify + GA4 + Google Ads conversion experience; show us at least one project where you tracked conversions inside a third-party iframe/widget. UK/EU consent experience preferred. Healthcare experience a plus. Note: no remarketing/audience tags. This is a healthcare site and Google prohibits health-condition audiences. Requirement to start immediately and complete within 3 days.
