Why can't I just put my GA4 tag on the Microsoft Bookings page?

The Bookings page lives on Microsoft's domain and you cannot add scripts to it, so GA4, Tag Manager and ad pixels never see the booking. With BookingsXP the booking happens inside a widget on your own page, and the loader reports each step to the tags you already have there.

Do I need Google Tag Manager?

No. If gtag.js is on your page, add your GA4 measurement ID in the widget's Tracking settings and the widget sends GA4 events directly. Tag Manager is the more flexible route: every step is pushed to the dataLayer as bookingsxp. , so you can build any trigger you like.

Will the booking count as a Google Ads conversion?

Yes, on Pro and Business. Enter your conversion ID and label and the widget fires the conversion when Microsoft Bookings confirms the booking, with the booking ID as the transaction ID to avoid duplicates. Your Google tag must be on the page. Turn on enhanced conversions to add the visitor's email, hashed with SHA-256 in the browser.

Where does the source information show up for my team?

In the booking itself. BookingsXP writes a short block into the booking notes with the reference, source, medium, campaign, keyword, first page, referrer and which ad click ID was present. Microsoft Bookings keeps it with the appointment, so staff see it in Outlook, Teams and the Bookings app without logging in anywhere else.

No. The loader sets no cookies. It keeps the last campaign touch in your site's local storage for 90 days so a visitor who clicks an ad today and books next week is still attributed, and it reads only the _ga, _fbp and _fbc cookies your own tags already set. The BookingsXP dashboard counts visits with a random per-visit ID and stores no names, emails or IP addresses.

How does it handle consent and Global Privacy Control?

If the browser sends Global Privacy Control, or your consent tool sets window.bxpConsent = false, the loader sends only the page path and the referrer's domain, and deletes any stored campaign touch. Ad conversions fire only when the platform's own tag is on the page, so your consent setup for those tags still applies.

Is the RefId parameter enough?

Not on its own. People have reported that ?RefId= tracking on Bookings links is unreliable, and even when the value is stored it does not appear in the calendar event your staff open. BookingsXP still sends its BXP reference as Microsoft's tracking data, but it also writes the source into the notes, where people can read it.

Tracking & analytics

Know which ads and pages book appointments

Microsoft Bookings has no analytics and no conversion tracking. BookingsXP reports every step of the booking to GA4, Tag Manager and your ad platforms, and writes the source of each booking into its notes in Microsoft Bookings.

The problem

The booking happens where your tags cannot see it

On Microsoft Q&A, the question “Microsoft Bookings – Analytics” has more than 70 “I have the same question” votes. It has been open since 2020, it is now locked, and Microsoft has not answered it.

01
Your tags cannot run there
The Bookings page is on Microsoft's domain. You cannot add GA4, Tag Manager, the Google tag or a Meta pixel to it, so the visit you paid for ends at the link.
02
There is no conversion to count
Bookings sends no event when someone books, so Google Ads and Meta cannot learn which clicks turn into appointments, and automated bidding has no booking signal to work from.
03
The source is lost
The appointment in Outlook says who booked and when, not whether they came from an ad, a search or a newsletter. The RefId workaround is reported unreliable, and its value never appears in the calendar event.

Events

What the widget sends, and where

Every step is pushed to your page's dataLayer as bookingsxp.<event> and dispatched as a bookingsxp:<event> DOM event. Four steps also go straight to GA4, and a confirmed booking fires your ad conversions.

Widget events, their dataLayer and GA4 names, and the ad platform events they fire
dataLayer event	When	GA4 event	Ad platforms (Pro)
bookingsxp.widget_viewed	The widget came into view	bookingsxp_view	Meta ViewContent
bookingsxp.service_selected	A service was picked	Not sent	None
bookingsxp.staff_selected	A person was picked (if offered)	Not sent	None
bookingsxp.date_selected	A day was picked	Not sent	None
bookingsxp.slot_selected	A time was picked	bookingsxp_slot	None
bookingsxp.form_started	The visitor started typing their details	bookingsxp_form_start	None
bookingsxp.booking_submitted	The form was sent	Not sent	None
bookingsxp.booking_completed	Microsoft Bookings confirmed the booking	generate_lead + bookingsxp_booked	Google Ads conversion, Meta Schedule, LinkedIn conversion
bookingsxp.booking_failed	The booking could not be made	Not sent	None
bookingsxp.no_availability	The visitor found no open times	Not sent	None

GA4 events are sent directly when gtag.js is on the page and you add your measurement ID; otherwise use Tag Manager on the dataLayer events. value and currency come from the service price when Bookings has one.
Google Ads, Meta and LinkedIn fire only when that platform's tag is already on the page and its ID is set in the widget. Google Ads gets the booking ID as the transaction ID; Meta gets it as the event ID, so duplicates are dropped.

Attribution

The source, inside the booking

Turn on “Write source & campaign into the booking notes” and every booking carries a short block your team reads in Outlook: the campaign, the keyword, the page someone first landed on and which ad they clicked. No personal data goes into it.

Notes

Left knee, running injury.

— Booked on your website · Ref BXP-7K3M9Q
Source: google / cpc · Campaign: spring-physio (Paid search)
Keyword: sports physio near me
First page: /physio?area=knee
Booked from: northwind.example/book
Referrer: google.com
Ad click: gclid

Written into the booking by BookingsXP. Microsoft Bookings keeps it with the appointment in Outlook, Teams and the Bookings app.

What is captured: utm_source, utm_medium, utm_campaign, utm_term and utm_content; the gclid, gbraid, wbraid, fbclid, msclkid, li_fat_id or ttclid click ID; the referrer; the first page; and the page the booking was made on.
First touch that counts: The loader remembers the last campaign visit for 90 days, so someone who clicks an ad on Monday and books from a bookmark on Friday is still credited to the ad. A plain return visit does not overwrite it.
GA4-style channels: Each booking is classified as Paid search, Paid social, Organic search, Organic social, Email, Referral, Direct or Other, the same grouping GA4 uses by default.
In Bookings' own export: Optionally, BookingsXP answers a custom question on your Bookings page, such as “How did you hear about us?”, with the source, and hides it from visitors. It then shows up in Microsoft's own reports and exports.
A reference on both sides: Each booking gets a reference like BXP-7K3M9Q, written into the notes and sent to Microsoft as the booking's tracking data, so you can match a booking in Outlook to its row in BookingsXP.

Privacy

Enhanced conversions without shipping raw emails

Better ad matching usually means sending a customer's email to an ad platform. BookingsXP hashes it first, in the visitor's browser, and only when you ask it to.

Hashed in the browser: With enhanced conversions on, the widget computes a SHA-256 hash of the email on the visitor's device and sends Google Ads only the hash, as sha256_email_address. The raw address never goes to Google.
Only on a confirmed booking: The hash exists only on booking_completed, and only for widgets with enhanced conversions switched on. Update your privacy notice before you turn it on.
Global Privacy Control honoured: When the browser sends GPC, or your consent tool sets window.bxpConsent = false, the loader sends only the page path and the referrer's domain, and forgets any stored campaign touch.
No cookies set: The loader sets no cookies. It reads only the _ga, _fbp and _fbc cookies your own tags already set, so GA4 and Meta can join the booking to the visit.

Setup

Set it up in Tag Manager

Add the widget, then point a Custom Event trigger at bookingsxp.booking_completed. The step-by-step guide is in GTM and GA4 setup, with platform notes for Google Tag Manager and Google Ads.

Thank-you page

Send people to your own confirmation page

Set a redirect URL in the widget and, after a confirmed booking, the page moves to it. Tags that only fire on a thank-you page view keep working. The move waits 600 ms so pixels finish sending.

Redirect URL

Text

https://northwind.example/thank-you?id={booking_id}&service={service}&start={start}

Where the visitor lands

Text

https://northwind.example/thank-you?id=AAMkADk2ZTJh…&service=Initial%20assessment&start=2026-10-14T14%3A15%3A00.000Z

{booking_id} is Microsoft's booking ID, {service} the service name and {start} the start time in ISO format, all URL-encoded. Relative URLs work, and a redirect-url attribute on the element overrides the saved setting for one page.
