Instance Property


A Base64-encoded string used to contain your application-specific data.


DOMString applicationData;


Use this property to contain 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 must be a valid Base64-encoded string; otherwise, it is ignored.
