You can now pass parameters through links in your funnel, either from values collected during the funnel (like quiz answers or email) or from the session itself (like app_user_id).
This is useful when you need to route users to your app or web product after completing a funnel and identify them on the other side. For example, you can configure a button on your final page to link to your app with the user's app_user_id and email embedded in the URL.
A common setup for free funnels: the user goes through your quiz or onboarding flow, submits their email (which fires the Registration Webhook to your backend), and then taps a deep link button that carries their app_user_id into your app. Your backend already has their account ready from the webhook, so the experience is seamless.
Variables are inserted using {{variableName}} syntax. Any variable collected in the funnel, including derived variables you create from quiz answers, can be passed through.
