Maybe I have a weird problem. In any case, I can't find a solution.

In my company we use software that does not support synchronized interfaces. No connection to our Google account, Zapier, HubSpot or anything else. My goal is not to manually enter new contacts. I get new contacts by booking appointments with Calendly.
 

I then need this information as a CSV or Excel file so that I can then transfer it, at least not manually, using the import function of our "stupid" software.
 

I manage to collect new Calendly bookings into a Google spreadsheet. And I can also create a URL that downloads the spreadsheet directly when called.
 

But I can't manage this stuff:

- only the most recent contact is downloaded (one spreadsheet per contact?)

- the download is triggered automatically
 

Of course I could receive a new email with the URL as the content, which triggers a download, but if I don't click on the link in time, the contact will already be overwritten by a new one.

Does it make sense? Difficult to explain. The goal is: new Calendly booking --> automatically download contact information as a csv.
