Use this property for additional data as may be appropriate for your website. For example, the application data may be a shopping cart identifier or an order number that your back end will need to identify this transaction.

You are responsible for sending the full application data to your server, if needed.

The application data string must be Base64-encoded; otherwise, it is ignored.
