Can I send parameters in push notifications to toast (Windows Phone)?

Question

I have a case in my app where I need to send a push notification to a user device when the application is offline and appears as a toast notification.

I need when the user clicks on the toast message to navigate to a specific page in my application depending on the message. I know that this is available in toast notifications but can I send parameters from my server to the toast to determine the page?

Of course you can.

The XML of the toast notification you send from your server looks like this:

 <?xml version="1.0" encoding="utf-8"?>
 <wp:Notification xmlns:wp="WPNotification">
     <wp:Toast>
         <wp:Text1>[string]</wp:Text1>
         <wp:Text2>[string]</wp:Text2>
         <wp:Param>[string]</wp:Param>
     </wp:Toast>
   </wp:Notification>;

You use the Param parameter to send parameters to your app :

You can use the Param element to deep link to a specific screen in your app. Here are the allowed formats. Any string used for the following examples must be 256 characters or less.

• /page1.xaml – Defines the screen to navigate to in the app when the app starts. The string must begin with a "/".
• /page1.xaml?value1=1234 &value2=9876 – Defines the screen to navigate to when the app starts, along with name/value pairs of info. The string must begin with a "/".
• ?value1=1234 &value2=9876 – Contains name/value pairs of info passed to the default start screen of the app. The string must begin with a "?".

Hi Eran, just a question, I need the value in <wp:Text1> in the page I'm navigating from <wp:Param> Do I need to add this value into <wp:Param> as well? Or do I have some way to get it from OnNavigatedTo method in the desired page? Many thanks – Coxcomb

@Coxcomb From the docs, it doesn't look like you have access to the Text1 value of the notification in OnNavigatedTo, so you might have to add it to the Param. – Immemorial

Yes this is valid for all WP versions AFAIK. – Seguidilla

It looks like if you have a WP app compatible WP 8.0 / 8.1 / 10.0, on some end devices under WP 10, the <wp:Param>[string]</wp:Param> is not taken into account anymore. The onNavigatedTo() method doesn't show it (in your NavigationEventArgs, the URI has no parameters)... Any reason why? – Contestation
