Hi Luke,
You might have heard of this but just to confirm.
An example of the code goes as such.
Send Message to Website
Receive Message on Website
ThunkableWebviewerExtension.receiveMessage(function(message) {
// Do something with your message
alert(message)
});
Send a Message From Your Website to Thunkable
Receive Message from Website
ThunkableWebviewerExtension.postMessage('hello world');
Happy Coding,
Jay
