When calendly is integrated with zoom, the payload of the location field changes. The calendly docs do not document this, but speaking with calendly support

this is in fact intended behavior. 

The payload changes from {type, location, additional_info} to {data, join_url, status, type}.

The feature request here, would be to map join_url to the current fivetran location field. This way we track zoom urls as the meeting location. Right now, fivetran does not map the change and location is null for zoom events
