Fallbacks
Configure safe destinations for mobile failures, unsupported devices, and inactive links.
Fallback types
- Fallback URL: general mobile or web fallback.
- Android package: derives a Google Play URL when no fallback URL is supplied.
- iOS Store URL: used when no general fallback overrides it.
- Expiration redirect: preferred when lifecycle rules block the link.
Priority
Explicit device targets affect the attempted destination. The fallback URL takes priority over a derived store URL. For a blocked link, the expiration redirect has the highest priority.
Practice
Use HTTPS URLs, test installed and non-installed states independently, and avoid redirecting a fallback back to the same Smart Link.
