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 when you include a device token 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.
