After buyers click Checkout with PayPal, call SetExpressCheckout to begin a PayPal
payment. Then, redirect the buyer’s browser to PayPal. Include the device token from the library
and the checkout token from SetExpressCheckout as URL parameters.
PayPal displays the mobile PayPal log-in page with your redirect to PayPal. Buyers enter an
email address and password or a mobile phone number and mobile PIN to log in to PayPal.
