HubSpot Webinar Integration Setup (2026 Guide)

If you use HubSpot CRM, you’re probably already trying to keep your marketing and sales activities in one place. That way, you can stay organized, follow up consistently, and see what’s working without piecing things together across tools.

Webinars can fit in nicely, but only if your webinar platform is properly connected to HubSpot. The good news is the setup and syncing takes just a few seconds.

A proper HubSpot webinar integration solves the common “post-webinar chaos” by making webinar data usable inside HubSpot, so you can build lists, trigger workflows, and follow up based on what people actually did, rather than what you hope happened.

In this blog, you’ll learn how to integrate webinars with HubSpot CRM in a way that stays clean and manageable, whether you’re running webinars as a team or setting things up solo.

What “webinar integration with HubSpot” actually means?

When people search for “HubSpot webinar integration,” they’re usually looking for one thing: reliable automation. The integration is doing its job when HubSpot can clearly and easily show who registered, who attended, what should happen next, and much more, without any manual exporting in between.

Manual imports are where things get messy. They make it easy to introduce errors like duplicates or overwritten fields; they’re not ideal with GDPR when a CSV with personal data lives on someone’s laptop and waste time on tasks like exporting, cleaning, importing, and double-checking everything.

A good setup typically includes:

• Registrations syncing into HubSpot contacts, without duplicates or missing details

• Attendance syncing during the webinar, so you can separate attendees and no-shows

• Webinar activity showing up on the contact record, so you can see interactions like poll answers, and understand intent at a glance

• HubSpot follow-up running automatically, based on whether someone attended or missed the webinar

You can do more than this, especially with deeper engagement data, but these basics are what make webinars scalable in HubSpot.

1. Connect WebinarGeek to HubSpot CRM (it’s really just a few clicks)

You don’t need to be tech savvy to set up the WebinarGeek and HubSpot integration, because the connection is designed to be straightforward. In your WebinarGeek account, you connect HubSpot, confirm the right HubSpot portal, and you’re basically done. It really is just a few clicks.

2. Decide what you want HubSpot to know about each contact after a webinar

Once you’ve connected WebinarGeek and HubSpot, the real question becomes, “What should HubSpot be able to tell you at a glance?”

At minimum, you want registrations to show up automatically, so your contacts stay up to date without manual work. But the real value is what comes next: WebinarGeek can also send viewing behavior and viewer actions to HubSpot as events, including things like polls, calls to action, questions, evaluation forms, and watch time.

That means you’re not stuck with “they registered” as your only signal. You can see whether someone actually watched, how engaged they were, and what they interacted with, which is what makes follow-up feel relevant instead of generic.

One practical note that saves confusion later: standard registration fields can be synced as proper contact data, but custom registration fields are only included as timeline properties, so you can view them, but you cannot use them for workflows or personalization in HubSpot.

3. Make attendance the centre of your workflow logic

Registrations tell you someone was interested enough to sign up, but attendance tells you something much more useful: they showed up, gave you their time, and are far more likely to take the next step. When attendance is available in HubSpot, follow-up becomes simple and more relevant.

Attendees can get a recap and next steps while the webinar is still fresh, and no-shows can get the replay with a short prompt to catch up. If you also sync webinar interactions, like poll answers or questions, HubSpot gives you even more context, so you can segment based on what people engaged with, not just whether they were there.

A straightforward setup that works well in HubSpot is to build two lists and two workflows:

• One list and workflow for attendees, focused on recap and next steps

• One list and workflow for no-shows, focused on replay and a gentle reminder

If you want follow-ups that feel even more tailored, watch time segmentation is a simple upgrade. Think “watched 30%, 60%, 90%” and match your message to their level of interest.

4. Test everything before your next webinar

Before you run a campaign webinar, do a quick test so you can trust the flow. Register with a test email address, confirm the contact record updates, and check that the webinar activity is visible where you expect it. Then run a short internal test session, and confirm attendance updates after the webinar.

Ready to connect HubSpot with your webinars?

If you want webinar registrations and attendance to sync into HubSpot without manual exports, the easiest next step is to try it with a real test registration.

Start a WebinarGeek trial, then connect HubSpot inside your WebinarGeek account, and run a short test webinar to confirm the sync.
