is there any possibility to fetch the unbounce (lead) data to looker studio by using direct or 3rd party tool? if yes ,please provide details.. shall we need to take a pro account for the service?
Do you mean data from this company? https://unbounce.com/
Do they make data available to their customers? If so, it should be possible to download it and make it available to Looker Studio via Google Sheets.
I also notice that if I search for "unbounce looker studio" there are a couple of services that offer connectors to Looker Studio for Unbounce data, although of course I cannot vouch for these.
