Enter the page URL to navigate to when the ad is clicked. The URL you enter is used as-is, so you can freely use tracking parameters or deep links.

You don’t need to separate Android and iOS—universal links or app links work across platforms. Configure fallback handling for cases when the app is not installed through your deep link service provider.

You can enter tracking links from AppsFlyer, Adjust, Branch, etc. as-is. URLs are passed without modification.
