JavaScript configuration object

You can configure and render your messages using JavaScript as an alternative to HTML attributes. The PayPal JavaScript SDK messages component uses a JavaScript API that is similar to the API used by the buttons component.

Use the namespace attribute

Select this option if you're using a legacy integration for PayPal checkout that uses the data-namespace attribute when loading the JavaScript SDK messages component.
