When someone clicks a Calendly link, it automatically stores these query params as part of the event:
There are at least 4 ways to use this information in Marketo w/Zapier:
 in a Marketo "Create or Upload Lead" action you can tell it to map those fields back to Marketo fields. I would recommend your Marketo fields be string fields like LastCalendlyCampaign, LastCalendlySource, etc. since they will be overwritten.
 use a Marketo "Add Lead to List" action but condition it on a Zapier filter, so you add to a specific list based on Calendly information:
 use the other Zapier actions, like Formatter, to translate the UTM codes into List IDs, then use "Add Lead to List"
 other methods, like calling a webhook to simulate a Marketo form post
Thank you! I'm not sure the UTM params will work on a token- the links to the Calendly calendars are pulled in from Salesforce based on lead owner. Is there an easy way to append UTM params on a token?

Sure, just add another token or hard-code them. You already have to be building out the link, right?
