A: Currently it is not possible to create form from a notion database.
Formly connects directly with Google Sheets so you can connect with Google Sheets first.

Then you can connect your integrated Google Sheets with 3000+ applications (including Notion, HubSpot, ActiveCampaign etc) using Zapier, Pabbly, Make etc.
