+
+### Click behaviors
+
+When you build a push notification template, you can choose between three click behaviors, which determine what happens when a user taps on the mobile push:
+
+| Click behavior | Description                                                                                                                                                                                                                                                                                                            |
+| -------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| Open app       | Opens an app. You can specify a URL with or without merge tags to take the user to a specific screen with your app. If you don't enter a URL, this behavior will take the user to the app's home screen.                                                                                                               |
+| Open URL       | Opens the specified URL.                                                                                                                                                                                                                                                                                               |
+| Custom action  | Takes any value as text input. Your app determines how to handle the value. For example, you could enter a custom action of `open_settings`, and then instruct your application to open the settings application when a user taps the notification and the notification arrives with `click behavior = open_settings`. |
+
+## Test your mobile push template
+
+> info "Push tokens"
+> Push tokens are unique identifiers Segment associates with each profile. For push notifications, you'll need to configure identity resolution settings for the push tokens `ios.push_token` and `android.push_token`. Using the Profile explorer, you can find a profile's push tokens by opening a profile and then selecting the Identities tab. You can only send push notifications to profiles with push tokens enabled.
+
+Follow these steps to test your push notification:
+
+
+1. Choose a template to test:
+    - For new templates, select **Test** once you've finished building a template. 
+    - For existing templates, navigate to **Engage > Content > Push**, select the template you want to test, then click **Test**.
+2. Choose a messaging service and add a recipient.
+    - You can add recipients either by either their email address or user ID. 
+3. Click **Send test push**.
+
+Segment verifies that the the profile you're sending a test to has push tokens enabled, then sends the test. If the test push notification doesn't work as expected, confirm that the profile you're sending to has enabled push tokens.
+
+## Personalize with merge tags
+
+Personalize mobile push content in Engage using profile traits as merge tags in your messages.
+
+To personalize a push notification, click **Add merge tags** in the template builder and select the profile traits to include in your message.
+
+Engage inserts the selected traits inside merge tags based on cursor placement in the message. This allows you to personalize each push notification you send to recipients. You can also use [liquid templating](https://liquidjs.com/tags/if.html){:target="blank"} to create dynamic content in the template editor.
