Question from Reddit:
I want to run a Facebook ad to register people for Zoom meetings that I’ll set up weekly. I don’t have the Zoom Webinar functionality because for now I can do what I need in a meeting, and the Webinar feature costs extra.
Problem is, I haven’t found a way to track conversions with a Zoom “meeting.” And I’d like to avoid the Webinar Zoom upgrade for now. I’ve found info on how to set up a FB Pixel for a Zoom “Webinar,” but not for a Zoom “meeting.”
Is there a workaround for this? Thank you.
Answer from Nabil:
The short answer is:
The reason you can’t find a direct Pixel setup for a standard Zoom meeting registration is because, unlike the dedicated Zoom Webinar platform which allows for a thank you page that can load the Meta Pixel, the standard Zoom meeting registration flow typically happens entirely within the Zoom domain and doesn’t offer a customizable confirmation page to fire a client-side conversion event.
The immediate, reliable solution is to skip the browser-based Pixel entirely and use a server-side integration via the Facebook Conversions API to send the conversion data directly from Zoom’s confirmation system to Meta.
The long answer is:
This is a classic tracking challenge where a third-party platform’s process – in this case, Zoom’s standard meeting registration – breaks the traditional client-side Pixel tracking.
When a user registers for a Zoom meeting, the confirmation event is handled on a Zoom-owned domain page that you cannot inject your Meta Pixel code into, meaning your browser-based tracking setup (GTM and the Pixel) never gets a chance to see the conversion and attribute it to your ad.
To solve this without needing the Zoom Webinar upgrade, you need to implement a server-side solution that leverages the Zoom Meeting API and the Facebook Conversions API.
Here’s the excellent solution: Your ad links to a dedicated landing page on your own domain where the user clicks a button to open the Zoom registration link.
While the user is registering on Zoom’s site, your systems are dormant.
The moment a registration is successfully completed, Zoom has a powerful tool called the Zoom Meeting API that allows you to receive a webhook notification or periodically check for new registrants.
You use this Zoom Meeting API to extract the new registrant’s email address and the time of registration.
This data is then sent to a server-side tagging environment, such as one hosted on Stape or Google Cloud Platform.
Within this server environment, you take the registrant’s email, apply a one-way hashing function to it for privacy (a requirement for Meta), and then use the Facebook Conversions API to send a custom Lead or CompleteRegistration event directly to Meta.
Crucially, because this event is sent server-side, it’s not affected by browser limitations, ad blockers, or the lack of a thank you page on the Zoom domain.
By combining this lead data with the Facebook click ID (which you should capture on your initial landing page using GTM and pass through to your server), Meta can accurately match the conversion to the user who clicked your ad and give credit where it’s due, providing you with reliable reporting in Ads Manager for your standard Zoom meetings.
You use Google Tag Manager on your own landing page only to ensure you capture the necessary click information for Meta to use in the attribution process.
This server-side integration is the only truly reliable way to track conversions that happen off-site without a customizable confirmation page.
