beforeRedirect Callback
The beforeRedirect callback is invoked before browser redirects occur during the payment flow. The return value of the callback will be stored until the browser is returned to the merchant page. The value can be recovered with the afterRedirect callback.
Payment method such as PayPal requires the browser to be redirected away from a merchant page.
