Configure push notification message content

Configure push notification message content and select which mobile application receives notifications. You can configure critical alert notifications, customize the message appearance, and determine the deep link used when users tap the notification.

始める前に

To configure push notification message content, you must generate a deep link using the mobile deep link generator. For more information, see Deep linking for mobile.

Role required: admin

このタスクについて

Complete the Push Message Content form to:

• Name the notification
• Select the mobile app that the notification is sent to
• Optionally customize the appearance of the notification message
• Determine the deep link used when users tap the notification

Push notification message content supports up to three additional fields. If these fields are used as optional text slots, the slots can display fields from the source record.

注:

The text slots are fixed on the mobile app, so you cannot change their location or size. Each slot maps to a Status, Identifier, and Description within the JSON object in the push notification message content script.

Mobile UI styles are also available for additional fields. For more information around styling, see Mobile UI styles.

手順

1. Navigate to All > System Notification > Push > Push Message Content.
2. Select New.
3. In the Push Message Content form, fill in the following fields:

   表 : 1. Push Message Content form

   Field	Description
   Name	String value for this record. 注: This name is not visible in the notification, it is only a reference for use during configuration.
   Push app	References the mobile app you want to send a notification to. Use ServiceNow mobile Application for Mobile Agent. Use ServiceNow Request Application for Now Mobile app.
   Push Message Generation	The script block that contains the notification link. In the script block, the JSON object must return a link and a Link key must exist. The key should have a corresponding deep link value generated through the mobile deep link generator.

   This example shows the completed form and a JSON object with the appropriate Link key and a corresponding deep link value.
4. オプション: Add additional fields to the notification content, such as a text slot.

   In the Push Message Generation script block, create a layout field object for each field.

   1. Instantiate a notification layout object.

      var layoutGen = new global.NotificationLayoutFieldGenerator();

   2. Use the notification layout script and include the global application scope to generate layout fields.
      To learn more about script includes, see Script Includes.

      注:

      Do not modify the notification layout generator script include.
   3. Create the layout field.
      Each layout field requires a Table, Sys_Id, and a Column.

      注:

      The Table and Sys_Id values should come directly from the current record using current.getTableName() and current.sys_id. The Column value must exist for the desired table and match the dictionary column name exactly.

      var text_01 = layoutGen.layoutField(current.getTableName(), current.sys_id, "priority");

   4. Pass the layout fields into the original JSON object as another object.

      The mobile applications listen for the optional Layout key, which is an object that contains the desired additional fields. In the Layout object, associate each additional field with the Status, Identifier, or Description keys. The following example is available as a reference.

      (function buildJSON( /*GlideRecord*/ current, /*String*/ message, /*Object*/ attributes) { 
      
          var layoutGen = new global.NotificationLayoutFieldGenerator(); 
          var text_01 = layoutGen.layoutField(current.getTableName(), current.sys_id, "priority"); 
          var text_02 = layoutGen.layoutField(current.getTableName(), current.sys_id, "state"); 
          var text_03 = layoutGen.layoutField(current.getTableName(), current.sys_id, "short_description"); 
      
          var deepLinkGenerator = new global.MobileDeepLinkGenerator("Request"); 
          var link = deepLinkGenerator.getFormScreenLink("b71040b1533a33007bc2ddeeff7b1221", current.getTableName(), current.getValue("sys_id")); 
      
          var json = { 
      
              "Link": link, 
      
              "Layout": { 
      
                  "Status": text_01, 
      
                  "Identifier": text_02, 
      
                  "Description": text_03 
      
              } 
      
          }; 
      
          return json;
      
      })(current, message, attributes);

5. オプション: Add a customized notification title.
   If you don't add a customized notification title, the notification displays the default mobile app name.

   

   In the Push Message Generation script block, add the following example code in the json section:

   var json= {};
   var msg_title  = "System updates!";
   json= {
     "android_title" : msg_title,
     "aps": {
       "alert": {
         "title": msg_title,
       }
     }
   

   The elements in the sample JSON code are as follows:

   • The msg_title variable called System updates! is the notification title name that applies to both iOS and Android.
   • The nodejson["android_title"] is the variable for Android.
   • The node json["aps"]["alert"]["title"] is the variable for iOS.
6. Add the following code to activate Android devices to wake up, so that notifications can be triggered.

   As users use both iOS and Android devices you must add this code. The JSON entry in the code is a returned dictionary name value from the scripting.

   Android specific fields that control message delivery are supported under sncGoogleKeys. For more information, see Firebase Cloud Messaging HTTP Protocol.

   注:

   The priority parameter is set to high to wake up Android devices, if a device is in sleep mode. This parameter helps to deliver critical alerts to end users.

   json["sncGoogleKeys"] = {
       "priority": "high",
       "android": {
         "priority": "high"
       }
   }
   

7. Select Update.

タスクの結果

You created a push notification message content record that contains a deep link.

After configuring push notification message content, it must be paired with a push notification message record. For more information on configuring a push notification message, see Configure a push notification message.
