+### PropositionItem.track
+
+A unified tracking API is available for any proposition item (Content Cards, HTML, JSON, code-based items). You can use the same track() method regardless of content type, making your code more consistent and maintainable.
+
+#### Using PropositionItem.track (recommended)
+
+**Syntax**
+
+```javascript
+// Track display event
+propositionItem.track(MessagingEdgeEventType.DISPLAY);
+
+// Track interaction with custom data + event + optional tokens
+propositionItem.track(
+  interaction /* string | null */, 
+  MessagingEdgeEventType.INTERACT /* enum value */, 
+  [/* tokens */] /* string[] | null */
+);
+```
+
+When using `getPropositionsForSurfaces`, the returned objects can be wrapped with `MessagingProposition` to get typed items and convenient tracking via `PropositionItem.track(...)`.
+
+```javascript
+import { Messaging, MessagingProposition, MessagingEdgeEventType } from '@adobe/react-native-aepmessaging';
+
+const SURFACES = ['mobileapp://my-surface'];
+const messages = await Messaging.getPropositionsForSurfaces(SURFACES);
+
+for (const surface of SURFACES) {
+  const propositions = messages[surface] || [];
+
+  for (const proposition of propositions) {
+    const msgProp = new MessagingProposition(proposition);
+
+    if (msgProp.items.length > 0) {
+      const propositionItem = msgProp.items[0];
+
+      // Track interaction with custom data
+         propositionItem.track('content_card_clicked', MessagingEdgeEventType.INTERACT, null);
+     // Track with tokens for sub-item tracking
+        propositionItem.track('button_click', MessagingEdgeEventType.INTERACT, ['token-1', 'token-2']);
+    }
+  }
+}
+```

+### handleJavascriptMessage
+
+Registers a javascript interface for the provided handler name to the WebView associated with the InAppMessage presentation to handle Javascript messages. When the registered handlers are executed via the HTML the result will be passed back to the associated handler.
+
+**Syntax**
+
+```typescript
+handleJavascriptMessage(handlerName: string, handler: (content: string) => void);
+```
+
+**Example**
+
+It can be used for the native handling of JavaScript events. Please refer to the [tutorial](./tutorials/In-App%20Messaging.md#native-handling-of-javascript-events) for more information.

+# Native handling of JavaScript events
+
+You can handle events from in-app message interactions natively within your application by completing the following steps:
+- [Implement and assign a `Messaging Delegate`](#implement-and-assign-a-messaging-delegate)
+- [Register a JavaScript handler for your In-App Message](#register-a-javascript-handler-for-your-in-app-message)
+- [Post the JavaScript message from your In-App Message](#post-the-javascript-message-from-your-in-app-message)
+
+## Implement and assign a `Messaging Delegate`
+
+To register a JavaScript event handler with a Message object, you will first need to implement and set a MessagingDelegate.
+Please read the [documentation](../README.md/#programmatically-control-the-display-of-in-app-messages) for more detailed instructions on implementing and using a MessagingDelegate.
+
+## Register a JavaScript handler for your In-App Message
+
+In the `onShow` function of `MessagingDelegate`, call `handleJavascriptMessage(handlerName: string, handler: (content: string) => void)` to register your handler.
+
+The name of the message you intend to pass from the JavaScript side should be specified in the first parameter.
+
+### Example
+
+```typescript
+Messaging.setMessagingDelegate({
+    onShow: msg => {
+      console.log('show', msg);
+      msg.handleJavascriptMessage(
+        'myInappCallback',
+        (content) => {
+          console.log('Received webview content:', content);
+        }
+      );
+    }
+  });
+```
+
+## Post the JavaScript message from your In-App Message
+
+Now that the in-app message has been displayed, the final step is to post the JavaScript message.
+
+Continuing from the previous example, the developer is going to post the `myInappCallback` message from their HTML, which will in turn call the handler previously configured:
+
+```html
+<html>
+    <head>
+        <script type="text/javascript">
+            function callNative(action) {
+                try {
+                    // the name of the message handler is the same name that must be registered in  react native code.
+                    // in this case the message name is "myInappCallback"
+                    webkit.messageHandlers.myInappCallback.postMessage(action);
+                } catch(err) {
+                    console.log('The native context does not exist yet'); }
+                }
+            </script>
+    </head>
+    <body>
+        <button onclick="callNative('callbacks are cool!')">Native callback!</button>
+    </body>
+</html>
+```
+
+Note: (The above HTML is not representative of a valid in-app message, and is intended only to demonstrate how to post the JavaScript message).
+
+When the user clicks the button inside of this in-app message, the handler configured in the previous step will be called. The handler will send an Experience Event tracking the interaction, and print the following message to the console:
+
+```bash
+JavaScript body passed to react native callback: callbacks are cool!
+```
