Deferred deep linking

A tracking link can carry a destination. When a user taps the link, installs, and opens the app for the first time, the resolver hands that destination back as deep_link— so you can route them to exactly where the ad promised (a specific paywall, a creator profile, a promo), even though the app was only just installed. That's the deferred deep-link pattern.

1. Set a destination on the link

In Links → Create link, fill the destinationfield with your app's deep-link path or URL (whatever your router understands, e.g. myapp://paywall/summer). Leave it blank and deep_link simply comes back null.

2. Handle it on first launch

The first-launch snippet already receives it in the resolve response — just act on it:

// The resolve call already returns deep_link — just act on it.
if let deep = j["deep_link"] as? String, let url = URL(string: deep) {
  // route to the matching screen, e.g. a specific paywall or creator profile
  Router.open(url)
}
