Webflow Calendly integration fails to auto-populate form fields

Other Questions Calendly
1

I have successfully integrated Calendly into my Webflow site and the basic functionality works fine. I’m trying to automatically populate the booking form with user information that I already have available.

I found documentation about passing parameters to pre-fill invitee details, so I modified my booking URL to include the necessary data:

mysite.com/schedule-appointment?firstname=John%20Smith&[email protected]

The URL structure appears correct and the parameters are being passed, but when users click the link, the Calendly form still shows up empty. The name and email fields aren’t getting filled automatically as expected.

Has anyone encountered this issue before? I’m wondering if there’s something specific about how Webflow handles these URL parameters or if I’m missing a configuration step. Any suggestions would be really helpful!

Had the same issue when I was setting up Calendly. The parameter names have to match exactly - use name and email instead of firstname and contact. Your URL should look like mysite.com/schedule-appointment?name=John%20Smith&[email protected]. Also check that prefilling is turned on in your event settings - I missed that and it drove me crazy. If you’re using inline embed, make sure your embed code has the right data attributes too.
