Custom URL Scheme

Updated 29 July 2021


Custom URL schemes provide a way to reference inside your app. Users can open a custom URL in the browser or tap in any link. Other apps can also trigger your app to launch with specific context data; for example, a photo library app might display a specified image.

Custom URL scheme is one of the ways of deep linking, but apple strongly recommended universal deep linking. For more information on universal links, see Allowing Apps and Websites to Link to Your Content. Custom URL schemes are also being used to check if the application is installed or not.

Apple also supports common schemes associated with system apps, such as mailtotelsms, and facetime. You can define your own custom scheme and register your app to support it. URLs must start with your custom scheme name. Add parameters for any options your app supports.
