They allow you to go beyond visual construction and bring intelligence to your quiz flow. **With functions, it's possible to:** * Automatically send leads to external tools like RD Station and ActiveCampaign. * Create conditions to display different pages based on responses. * Capture and reuse variables throughout the funnel. * Trigger webhooks or redirect to external links. * And much more! This area is ideal for those who want to transform the quiz into a dynamic, automated, and strategic tool, whether for marketing, sales, or relationship building.
