Square Appointments doesn't send your bookings to Google Analytics 4 on its own, so GA4 shows traffic but not the actual conversions. With iBooker.online you paste one ID and every booking becomes a real GA4 event — here's how to set it up and verify it.
What you'll need
- A Square account connected to iBooker.online (via official OAuth).
- A GA4 property and its Measurement ID (looks like G-XXXXXXX).
Find your GA4 Measurement ID
- 1In Google Analytics, open Admin → Data streams.
- 2Select your web data stream (or create one for your domain).
- 3Copy the Measurement ID at the top — it starts with G-.
Connect it to your booking page
- 1Open your project in iBooker.online and go to the Analytics settings.
- 2Paste your G-XXXXXXX Measurement ID and save.
- 3Done — your branded booking page now loads GA4 and fires events automatically.
Which events GA4 will receive
iBooker.online tracks the whole journey, not just the final step. You'll see these GA4 events with rich parameters (service_name, service_price, currency, location_name, staff_name, duration, booking_id):
- select_location, select_service, select_staff — the funnel steps.
- begin_checkout — customer reached checkout.
- purchase — the appointment is booked (your main conversion, with value + currency).
Mark the booking as a key event (conversion)
- 1In GA4, go to Admin → Events (or Key events).
- 2Toggle purchase on as a Key event so it counts as a conversion.
- 3Optionally mark begin_checkout for funnel analysis.
Verify it's working
Open GA4 → Admin → DebugView (or the Realtime report), then make a test booking on your iBooker.online page. Within seconds you should see select_service, begin_checkout and purchase arrive with their parameters.
purchase uses your Square booking ID as the GA4 transaction_id, so the same booking is never counted twice.
