(non-null admin.auth.AndroidActionCodeSettings or undefined)

Defines the Android package name. This will try to open the link in an android app if it is installed. If installApp is passed, it specifies whether to install the Android app if the device supports it and the app is not already installed. If this field is provided without a packageName, an error is thrown explaining that the packageName must be provided in conjunction with this field. If minimumVersion is specified, and an older version of the app is installed, the user is taken to the Play Store to upgrade the app.


(string or undefined)

Defines the dynamic link domain to use for the current link if it is to be opened using Firebase Dynamic Links, as multiple dynamic link domains can be configured per project. This fields provides the ability explicitly choose one. If none is provided, the oldest domain is used by default.


(boolean or undefined)

Whether to open the link via a mobile app or a browser. The default is false. When set to true, the action code link is sent as a Universal Link or Android App Link and is opened by the app if installed. In the false case, the code is sent to the web widget first and then redirects to the app if installed.


(non-null admin.auth.iOSActionCodeSettings or undefined)

Defines the iOS bundle ID. This will try to open the link in an iOS app if it is installed.



Defines the link continue/state URL, which has different meanings in different contexts:

  • When the link is handled in the web action widgets, this is the deep link in the continueUrl query parameter.
  • When the link is handled in the app directly, this is the continueUrl query parameter in the deep link of the Dynamic Link.
