To configure tracking on Calendly event links requires a Calendly Pro account.
With Calendly Pro you get the ability to configure custom landing pages. With this ability, you can direct users to a tracked landing page containing your Wicked Reports tracking widget.
Add UTMs to your Destination URL
To track the initial link click, add the standard 5 UTM parameters to your Destination URL. In this case, your Calendly URL or the landing page URL where your calendar is embedded.
For example, if your booking link is https://calendly.com/you/20-minute-call and you're driving traffic from an email campaign to this URL, then your Destination URL might look like this:
Pass Tracking Through to the Thank You Page
On the Confirmation Page tab of the Calendly link setup, select Redirect to External Site as the On Confirmation action. Then, add your Thank You Page URL to the Redirect URL section.

Add the Wicked Tracking Code to your Thank You Page
The Wicked Tracking Code must be added to your Thank You Page for attribution to work.
After adding the Wicked Tracking Code to your Thank You Page, use the Tracking Validation Tool to ensure the code fires properly.
