Go to the 'Settings' tab of your funnel and click on one of the zap templates to open up Zapier. Sign up or log in if needed.

Use the API key from your Profile page to hook up your deal.ai account to Zapier.

The zap template should already have the deal.ai side of the zap set up, so all you need to do now is set up the other side of the zap with Google Sheets, Gmail, etc.
